London Irish have included Chris Hala'ufia and Ofisa Treviranus in their side to face London Wasps in the Aviva Premiership at Madejski Stadium on Sunday.
Treviranus comes in at openside flanker for Jebb Sinclair who is rested. Hala'ufia has recovered from the flu, which kept him out of last weekend's match, to be named at number eight. Sailosi Tagicakibau has recovered from a knee injury and is named as a replacement. Bryn Evans will captain the side.
"Wasps are a formidable team riding high in the Aviva Premiership so they'll give us a very tough test on Sunday," said London Irish director of rugby Brian Smith.
"In saying that we do pretty well against the top four teams at home and our boys are itching to put in a big performance for our supporters on Sunday."
Meanwhile, there are three changes for the men in black and gold from the Wasps side that beat Gloucester at Adams Park last weekend.
Two of those changes are in the pack. Will Taylor makes his first Aviva Premiership start, coming into the front row in the place of Phil Swainston who hasn't trained this week due to illness.
The other change sees Jonathan Poff return to the back-row following time out with injury, replacing Billy Vunipola, who is ruled out after picking up an injury whilst training with England.
That change sees Sam Jones move to eight, with Poff coming in at seven.
The one change in the backs sees Elliot Daly, who has spent the majority of this week with England, return to the side, starting at outside centre, alongside Chris Bell.
Form: London Irish's two game winning run in Aviva Premiership Rugby ended with their 16-40 defeat at Bath on Saturday.
