Full-back Israel Dagg and utility back Isaia Toeava will both start against the Springboks in Port Elizabeth on Saturday in perhaps their last chance to impress Henry at Test level after recovering from long-term leg injuries.
Loosehead prop Tony Woodcock also returns after a long-term foot injury, while fellow front rower John Afoa has recovered from a fractured eye socket that he sustained against the Springboks in Wellington last month.
"There is excitement across the board in the squad and every player will be looking to put in a big performance this weekend," Henry said.
"Playing the Springboks at home is always a massive occasion and with rugby World Cup spots also up for grabs, our players will be looking to put in a big performance."
The Springboks are reduced to playing for pride after losing all three of their matches to be out of the running for the southern hemisphere title.
