All over in Warsaw, and Greece go through! Czech Republic are group winners!
The final whistle goes in Wroclaw, and as it stands Czech Republic are going through. About a minute left in Warsaw, with Greece beating Russia.
BLASZCZYKOWSKI!!! The Poland captain's right-footed strike is bound for the top corner but Michal Kadlec leaps in to head it away! What heroics!
We're in the second or four added minutes now. Can Poland sign off on a high and break Czech hearts?
Czech substitution: Tomas Pekhart replaces Baros.
There is a bit of a scuffle as the substitution is being made. Poland have taken issue with how long it was taking Pilar to leave the field. Plasil and Blaszczykowski are both booked for their parts in it.
Czech substitution: Jan Rezik replaces Pilar.
Dudka thumps his free-kick right into the wall, but fromt he rebound a cross comes in that Mierzejewski heads on to the roof of the net. The flag was up for offside against the substitute.
Cech is lining up huis wall as Poland have a free-kick. Dudka might fancy a pop from here...
Czech Republic substitution: Frantisek Rajtoral replaces Jiracek.
Play is stopped while Jiracek is treated. He'll be ready to re-join play shortly.
Cech comes off his line to palm away a Poland corner. Piszczek catches the loose ball with a fierce half-volley that canons off of Jiracek's head!
Plasil sends in another teasing free-kick from the left, but it hooked away for a corner by Dudka.
Cech's long kick goes all the way through to Baros, but Tyton comes out of his area to make the interception before the striker can get it under control.
It's incredible to think that, after being roundly thumped 4-1 by Russia in their opening game, that Czech Republic would end up going through at their expense!
Poland substitution: Adrian Mierzejewski replaces Murawski.
So, as it stands now it's the Czechs and Greece who go through. Russia and Poland are going out!
GOAL!! Murawski gives the ball away and the Czech's break! Baros brings it forward before laying it off to Jiracek. The attacker cuts inside his marker and sidefoots a low finish past Tyton!
Still 1-0 in Warsaw. At the moment both Greece and Russia are going through.
Remember, Poland have never won a match at a European Championship finals before. They must do so now to progress.
Baros saunters through and had Gebre Selassie to his right, but he goes for goal and hits a tame shot at Tyton.
Sivok stoops to meet the free-kick at the far post and the low header rebounds off Tyton's legs! The ball ends up going out for a goal kick, and Poland can breathe again.
Another Czech free-kick on the left side of the area won by Pilar. Can the Czech's make one of these count?
Plasil's delivery is headed over the bar by Gebre Selassie.
Plasil's teasing delivery is only half-cleared by Poland, and Dudka concedes a free-kick on the other flank. Same again, but in reverse...
Rampaging run down the left flank by Limbersky and Wasilewski brings him down on the left-hand edge of the box. A booking for the Pole and a free-kick for the Czechs...
Dudka again flexing his muscle in midfiel. Yet to see a clear chance in this second half.
Pilar is sent flying into touch by dudka, who steps in with an uncompromising barge on the little Czech danger man.
Grosicki's first contribution is to concede a free-kick for a foul on Kolar, slightly harshly to be honest.
Great build-up from the Czechs, but Gebre Selassie makes it all go to waste by straying needlessly offside.
Poland substitution: Kamil Grosicki replaces Polanski.
This really is extraordinary. We have a little over 30 minutes left of football to play in Group A, and anything could happen. You've got to love tournament football.
Wasilewski hauls down a Czech player after he was beaten. The ball may pass, or the man may pass, but not both.
Again the Poles are dominant in the air as they defend a set piece.
Kolar and Pilar combine to work the ball to Baors, whose shot from the edge of the box is blocked for a corner.
The Czechs win a corner, which is well defended by Poland but the team in red retain possession.
In Warsaw, Roman Pavlyuchenko has replaced Aleksandr Kerzhakov for Russia, so they might actually score some goals now.
Pilar makes a great tackle on Blaszczykowski, and his reward is to get upended by Polanski as he sets off for the Polish goal! That's a booking for Polanski, it was right under the referee's nose.
The second half is underway! Now this match is truly win or bust for both teams.
Scratch that! Giorgos Karagounis has just scored for Greece in the dying moments of the first half against Russia! It will now be Russia and Greece going through if it stays this way.
The whistle blows to end the first half without any added time. We haven't had a goalless draw yet but as it stands we are on course for two in Group A. As it stands Russia and Czech Republic are going through.
The Czechs clear the initial corner and Piszczek's ambitious effort from miles out sails high into the crowd.
Poland come forward now and Murawski's shot takes a deflection.
Pilar beginning to exert a lot more influence as the first half enters the closing stages. The Wolfsburg midfielder bursts into the area from the left and has one shot blocked but lashes at the rebound. Tyton gets down to save it and grabs hold of the loose ball before Baors can pounce.
Good build-up from the Czechs as Pilar controls well ont he left. The ball is worked intot he path of Plasil 25 yards out, and his shot takes a deflection but Tyton is not going to be beaten by it. That's the Czechs' first shot on target.
Jiracek dinks a clver ball over the top right into the path of Baros's clever run. The striker is all on his own as he stretches out a boot to try and control the ball, but it's just a fraction too far ahead of him.
The ball is kicked out of play with Obraniak on the floor. Looks like he slipped over awkwardly on the sodden surface, but he's soon on his feet again.
Interesting period of play here. Both sides taking it in turns to nick the ball in midfield and then lose it themselves as they try to build an attack.
Cech has conceded five goals from only seven shots on target so far in this tournament.
Good play from Gebre Selassie and Jiracek wide on the right, but Murawski hustles them into having to settle for a throw-in.
The corner is whipped in to the near post for Kolac, who can only glance it tamely to Tyton.
Limbersky wins a corner for the Czechs as thunder and lightning arrives above the stadium.
Stubborn defending from Poland and now they hit Czech Republic on the break. They havwe numbers forward as Lukasz Piszczek bombs into the box, but the Czechs manage to regroup and snuff out the attack.
Obraniak tries a curling delivery from deep to Lewandowski but it sails comfortably into Cech's hands.
Plasil's delivery from deep is poor and Poland clear it easily.
Rafal Murawski is booked for holding back Baros in the centre circle as the striekr tried to turn him.
Sivok's clearance lands at the feet of Boenisch a good 30 yards from goal. That doesn't put the defender off and his low shot has to be tipped around the foot of the post by Petr Cech!
Great play by Blaszczykowski on the left, as he twists and turns away from three Czech players before playing the ball inside to a team-mate. He's a class act
Poland have already had six shots on goal (one on target), while the Czechs are yet to test Przemyslaw Tyton.
The Czechs are indeed beginning to see more of the ball now as the tempo finally begins to drop just a tad.
Still 0-0 in the Greece-Russia game with a quarter of an hour gone in Warsaw.
Eugen Polanski is played through but his strike from 20 yards is off target. Poland need to take one of these chances soon before Czech Republic get back into this game.
Michal Kadlec gets his head to the delivery at the near post to guide it away from goal. It falls to Sebastian Boenisch, who fires wide!
Limbersky is the first player to go into the book for a late clip of the heels on Blaszczykowski. Another Poland free-kick from the right...
There you go! Sloppy pass in the Czech defence and Lewandowski pounces on the loose ball. He shoots from the edge of the box, but Gebre Selassie does just enough to put him off and make him fire his left-footed strike wide!
The rain and the subsequent skiddy surface have meant neither side has been able to slow the tempo down. Surely they can't maintain this without mistakes being made for much longer?
Obrianiak set up eight shots for Poland in their last game against Russia – no Polish player has ever set up more in a single match at the Euros.
On the two previous occasions the Czech Republic have made it past the group stages, they have at least reached the semi-finals (1996 and 2004).
Blaszczykowski goes for goal... into the side netting again! That's the way to fray Polish nerves early on!
Jakub Blaszczykowski wins another free-kick on the right flank. All the big men come up for it...
Milan Baros is fouled for backing into his marker. The Czechs need a big perofmrance from their striker, who is yet to score in this tournament.
Theodor Gebre Selassie motors past his full-back into the area and pulls the ball back to Jaroslav Pilar who completely miscues his effort! High octane start to this match.
Right away David Limbersky fouls Robert Lewandowski on the right wing. Free-kick in a good position. Ludovic Obraniak whips it in and Dariusz Dudka hits the side netting! For a moment, the revved up home contingent of the crowd thought it was in!
Poland kick off and we're underway!
The anthems are belted out by both sets of fans, as you would expect on a night when so much is at stake. It's red-and-white in all four corners of the ground as we're about to get underway...
The two teams stride out on to the pitch in Wroclaw, where Poland lost the only other time they played here - to Italy back in November. It is absolutely chucking it down!
Poland have played more games at European Championships without winning than any other side (5). Only one host nation has ever failed to win a group stage match at the Euros (Austria in 2008). No side has ever had the same result in all three group stage matches at the Euros (Poland have had two 1-1s so far). No side has ever drawn all three group stage matches at a European Championships.
Only Peter Schmeichel (20) has conceded more goals at European Championship finals than Petr Cech (15). Cech has conceded five goals from only six shots on target so far in this tournament.
The referee for this clash is Scotland's Craig Thomson, who also took charge of the exciting 3-2 win for Portugal over Denmark on Wednesday.
Match odds: Czech Republic 9/4, Poland 5/4, Draw 12/5.
Czech boss Michal Bilek, who said before Rosicky was ruled out that the team was more confident with him in the side "We want to go to the quarter-final. Right now, it's one or the other and we will do our utmost to achieve this goal. Of course, we respect our opponent but we are not scared. We don't want to say goodbye to the Euros and we want to go through."
Poland coach Franciszek Smuda, who has presided over two draws at the tournament thus far: "We do not need to (be more attacking). The Italians only defend and they seem to able to win as well. Why shouldn't we? Our main aim is to stay focused and not commit any mistakes. This is the most important game of my life, I know this. We are not facing the same pressure that we were prior to our first match against Greece. But we know that it is hard to beat anyone here."
The resident pundits on Eurosport's nightly 'Euro 2012 Show' are hopeful that Poland can go through so as to keep at least one host nation interested and that, in the other match, Russia will "eat the Greek Tzatziki".
Head-to-head: Czech Republic have won 13 and lost just six of 23 internationals against Poland (including games played as the former Czechoslovakia). Poland’s six wins against the Czechs have come in their last six games on home turf against them. The Czechs have won three of their four previous competitive meetings with Poland (though one of them was by default after Poland withdrew from qualifying for the 1934 World Cup).
Poland coach Franciszek Smuda goes with an unchanged team, with midfielders Eugen Polanski and Dariusz Dudka recovering from injuries in a three-man central midfield that was the basis for a counter-attacking comeback 1-1 draw against Russia. Damien Perquis also recovers to start at the centre of defence, with French-born attacking midfielder Ludovic Obraniak keeping his place on the left wing.
Injured Czech Republic captain Tomas Rosicky misses out on in this decisive clash with an Achilles injury. The playmaker is replaced by Daniel Kolar in the creative role behind striker Milan Baros. Otherwise it's as you were for Michal Bilek's side.
Czech Republic: Petr Cech; Theodor Gebre Selassie, Michal Kadlec, Tomas Sivok, David Limbersky; Petr Jiracek, Tomas Hubschman, Jaroslav Plasil, Vaclav Pilar; Daniel Kolar; Milan Baros /// Poland: Przemyslaw Tyton; Lukasz Piszczek, Marcin Wasilewski, Damien Perquis, Sebastian Boenisch; Jakub Blaszczykowski, Dariusz Dudka, Eugen Polanski, Ludovic Obraniak; Rafal Murawski; Robert Lewandowski.
The situation is pretty simple for these two sides - a win for either side in this match would see them reach the quarter-finals, no matter what happens in Russia's match against Greece which will kick-off simultaneously in Warsaw.
