The final whistle goes, and West Brom mark Roy Hodgson's first anniversary at the club in some style. With four successive home defeats in the league, could this be the end for McCarthy?
Mick McCarthy must be very concerned about his future with this result.
Three minutes of added time to be played. Three minutes too many for Wolves.
West Brom subtitution: Graham Dorrans replaces Odemwingie.
GOAL!! WOLVES 1-5 WEST BROM!! Hat-trick for Odemwingie! Wolves caught on the break and Odemwingie is free at the far post to turn in the cross from the left!
O'Hara fires a crisp, low volley from 25 yards that's saved by Foster!

GOAL!! WOLVES 1-4 WEST BROM!! Wolves in complete disarray! Morrison wriggles his way around Johnson and pulls the ball back to Andrews, who has acres of space to fire home on his West Brom debut!
The way things stand, Wolves will be in the bottom three this evening. Losing by two clear goals puts them below Blackburn on goals scored.
Johnson makes a meal of a header back to his keeper and Fortune nips in between him and Hennessey, but can only prod his effort across the face of goal!
That's Odemwingie's sixth league goal of the season, and his fourth in four games against Wolves.
GOAL!! WOLVES 1-3 WEST BROM!! Cracking goal from West Brom that has surely won this derby! Ridgewell heads the corner back into the mixer and Olsson picks out Odemwingie in the six-yard box with a cheeky backheel flick. The striker hooks the ball home from close range for his second of the game!
Berra tracks Fortune's run and concedes a corner. Feels like there's another goal in this game.
West Brom substitution: Simon Cox replaces Thomas.

Olsson with his fifth career PL goal. His last three have all come in West Midlands Derbies.

Wolves substitution: Nenad Milijas replaces Edwards.
Well, Wolves have already come from behind once in this game. Can they do it again?
Olsson scores his second league goal of the seaosn, but he has to thank Hennessey. The Welsh keeepr had been enjoying a very good game until then, but that is unquestionably a howler.
GOAL!! WOLVES 1-2 WEST BROM!! Pandemonium in the Wolves box as they fail to clear the corner time and time again. The ball hits the post before Johnson hacks it high in the air. It lands inside the area and Olsson's tame shot slips through Hennessey's hands and over the line!
West Brom come forward from Morrison's pass and Fortune is on the right. He looks as though he is going to cross but goes for the near top corner and Hennessey makes a great reaction save!
Morrison turns defence into attack for West Brom with a simple shift of position and a pinged pass across to Odemwingie. Lovely stuff.
Wolves substitution: Christophe Berra replaces Sebastien Bassong. Looks like the on-loan defender has picked up an injury.
Wolves have now recovered more points from losing positions than any other team in the top flight this season (13). Only QPR (15) have dropped more points from winning positions than West Brom (14).
Wolves deal with the set piece well. Can they play their way back into this game?
The corner is curled in and Andrews meets it with a clean header that goes safely over the bar. The Baggies come again with a great run into the box and his cross is blocked for another corner.

West Brom dominated the first half both in terms of chances and possession, but it has been a lot more even since the break.

Great awareness from Fletcher to see the loose ball comes across the box and get his shot away! It deflects off the defender in front of him and goes wide for a corner, much to Foster's relief.
West Brom substitution: Keith Andrews replaced Paul Scharner at half-time. Apologies to the Irish debutant for missing that.

Just the one minute of added time at the end of the half.
Better from Wolves in the last five minutes or so. They are keeping possession well and not letting West Brom outnumber them in midfield, but they are still not creating any chances.
O'Hara tries to ping a ball down the left channel for Stephen Ward to chase, but it's just too long for the full-back's overlapping run.
Wolves will require a reshuffle at the break. Kevin Doyle has been virtually anonymous out wide on the right.
Olsson fouls a Wolves defender as he tries to win the ball back at a West Brom corner.
Odwemwingie surges at the Wolves box again and his strike is squirmed wide for a corner by Hennessey.
West Brom have their tails up now, and are still putting Wolves under pressure.
Well, let's amend that recent stat, shall we? Odemwingie has now scored in the three of his four matches against Wolves.
GOAL!! WOLVES 0-1 WEST BROM!! Great hold-up play from Fortune sees the ball worked wide to Odemwingie. The striker comes inside and his strike from the edge of the box deflects off Edwards's back side and through the keeper's legs! So unfortunate for Hennessey!
Good work from Morrison as he slips the ball to Fortune on the right. The low pass across the box is a good one but it's intercepted.
Odemwingie has scored in the last two games against Wolves.
Teed up for O'Hara and the strike is blocked by Odemwingie. The striker was surely fewer than 10 yards away as he charged out there.
Good counter-attack from Wolves as Fletcher feeds ebanks-Blake. The striker tries to return the favour but he's fouled by mulumbu beofre he can do so. Free-kick in a great position for the shot. Ben Foster shouts at his defenders to get a wall in place...
First Ebanks-Blake and then O'Hara have efforts blocked in the area, but Wolves do get another corner. west Brom are more decisive in their handling of that set piece.
O'Hara gets the game's first booking as play resumes.
Scharner still looks in some pain and he is hauled to his feet and off the field for treatment.

The corner falls to the feet of Ridgewell and Fletcher makes a vital block from the defender for another corner.
GREAT SAVE FROM HENNESSEY! Odwemingie feeds Thomas inside the box and the ball is laid off back to Scharner. The midfielder's strike takes a deflection off a Wolves defender and the keeper tips the shot over the bar! He must have seen that late too!
Thomas goes scamperng up the pitch on the counter and Edwards trips him as he goes past. Again the referee does not show a card, though he probably should have there.
Some good pressure from Wolves now, as they have two corners in quick succession but West Brom eventually clear their lines.
Odemwingie is played into the box and his strike is parried by Hennessey! The ball comes back to Odemwingie at an awkward hieght and he swipes his second effort over the bar!
Wolves have accumulated 21 points after 24 matches, exactly the same amount as they had at this stage in each of the previous two seasons. West Brom’s record after 24 matches (7 wins, 5 draws, 12 defeats) is identical to last year’s mark at the same juncture. They have scored seven fewer goals and conceded 11 fewer goals compared to that point in time.
Now Sylvan Ebanks-Blake goes down in the box, but it was after some good defending from Gareth MacAuley.
Edwards sneaks his way through two West Brom players and into the box, but went stumbling down in instalments as he did so. The appeals for a penalty are all coming from the crowd rather than the player himself.
The Black Country Derby is a tradition that is more than 123 years old in the English league and is therefore one of the oldest derbies in the world. Only one person in history, Frenchwoman Jeanne Calment, lived for 122 years.
Great early tempo from West Brom, but surely they can't keep this up for much longer? Peter Odemwingie is caught offside.
Fortune catches David Edwards late in the centre circle. Referee Lee Mason keeps his cards in his pocket.
In the opening 10 minutes, West Brom have enjoyed 67% of the possession. Debutant Liam Ridgewell shrugs Steven Fletcher off the ball and shields it out for a goal kick.
Foley gets the better of Thomas this time, blocking his cross at the byline and only at the expense of a throw.
Great skill from Fortune as he weaves his way into the box from the right and plays to the feet of Paul Scharner. The Austrian tries to improvise a backhell flick at goal but misses the ball.
West Brom hesitate in clearing their lines fromt he corner, but are given a reprieve as a foul from a Wolves player stops play.
First foray forward from Wolves. Matt Jarvis's mazy run ends with a first corner of the match for the home side.
Nice interplay down the left from West Brom. They want to get Thomas one-on-one with Kevin Foley at every opportunity.
West Brom have scored the highest percentage of goals in the opening 15 minutes of any team in the top flight.
Thomas again, this time from range as Marc-Antoine Fortune nods a long ball down to him. The low strike is wide of Hennessey's near post.
Great instinctive save from Hennessey. All he could do was spread himself as best he could and it was enough to stop Wolves conceding an early goal.
James Morrison's poor square pass across the Wolves box ricochets off a defender and into the path of JEROME THOMAS... Wayne Hennessey makes the save!
West Brom kick off and we're underway!
The players are walking out on to the pitch now on this snowy day in the Midlands. You can share your thoughts on the match - or just how glad you are to be inside in the warm - by getting in touch with me via Tiwtter @tony_mabert.
Steven Fletcher has scored nine PL goals this season – one short of his record of 10 last season. It is 14 years since a Scottish player has reached double figures in consecutive seasons in the division – both Kevin Gallacher and Duncan Ferguson achieved this feat in 1996-97 and 1997-98. West Brom's top scorer, Shane Long, has five goals so far this term.
Today's referee is Lee Mason. The Bolton official is one of only two who are yet to show a red card in the Premier League this season - the other is Mark Halsey. Expect him to let the game breath as much as possible, which should help make for a good derby. Mind you, Mason was the man that sent off Wolves’ Karl Henry after his vicious tackle on Wigan’s Jordi Gomez in October 2010. Wolves have lost their last four PL matches with Mason in charge.
Roy Hodgson: "Mick has done a magnificent job at Wolves. Mick took them up and then stayed in the Premier League but then people want to see you move on even further and the expectations go up. Unfortunately when you bring teams up, the barrier gets raised and, if you don't bring the players in to match that, then it can be very difficult. The world of football is full of people who do good jobs taking their teams up and then losing their job because they can't do as well in the league above.
Wolves boss Mick McCarthy: "People say these games or those games will decide the outcome of the season. I seem to remember being sat here last season, saying it might be the last kick of the season that it would go down to, maybe the last goal, the last point. That's how it turned out and maybe that will be the same again. These next few games are vitally important but it could go to the very last game, and it looks like it will because it is ever so tight in the bottom half of the table."
Interesting stats surrounding these two clubs compared to their positions a year ago. Hodgson took over at The Hawthorns on February 14 last year, with the Baggies five points clear of the relegation zone just as they are today. This time 12 months ago, Wolves were bottom of the table, and went on the survive on the final day of the season.
Head-to-head: This is the 148th Black Country derby in the league. As it stands, Wolves have won 52 to West Brom's 55. West Brom have won seven and lost only two of the last 12 meetings in all competitions against their local rivals, and four of their last six visits to Molineux. When they met at The Hawthorns back in October, the Baggies won 2-0.
Shane Long and Graham Dorrans have also both had fitness tests, but only make the West Brom bench. Long has been troubled by a back complaint and chest pains and has only been able to train on his own this week, while Dorrans is suffering from a hip problem. Manager Roy Hodgson gives first start to left-back Liam Ridgewell, though midfielder and fellow transfer deadline day signing Keith Andrews is only named among the substitutes. Chris Brunt (ankle) and Zoltan Gera (knee) are still out.
Central midfielders Jamie O'Hara (groin) and Dave Edwards (thigh) have both passed late fitness tests and start for Wolves. They are already without Emmanuel Frimpong, who returned to Arsenal after rupturing knee ligaments, and the suspended Karl Henry in that department of his side. Winger Michael Kightly (back) is also missing but right-back Kevin Foley has overcome an ankle problem and starts.
Wolves: Hennessey, Foley, Johnson, Bassong, Ward, Doyle, O'Hara, Edwards, Jarvis, Ebanks-Blake, Fletcher. Subs: De Vries, Stearman, Berra, Milijaš, Jonsson, Hammill, Hunt /// West Brom: Foster, Olsson, Ridgewell, Morrison, Reid, Thomas, Mulumbu, McAuley, Odemwingie, Fortune, Scharner. Subs: Tchoyi, Andrews, Long, Fulop, Dorrans, Jones, Cox.
Wolves can pull themselves three points clear of the relegation zone if they win the latest instalment of the Black Country derby. West Brom are five points above that clutch of teams battling against the drop, but they could do with a victory to put some more daylight between them and the relegation mire.
