Wasps director of rugby Dai Young has included six new faces in the starting line-up for Sunday's game.
Tom Varndell will start on the wing, with Matt Everard making his first competitive start of the season, after an impressive display off the bench in Cardiff last weekend.
With Marco Wentzel ruled out with a knock, Wasps have called up Josh Brown from London Scottish to fill the second-row, with the area already missing Tom Palmer and Joe Launchbury who are in the England side this weekend.
Having been rested last weekend, Ashley Johnson and Tom Lindsay are the other new starters coming back into the team.
Meanwhile, the Warriors are aiming to continue their momentum in the LV= Cup, as they top the Pool Two standings after the opening round of games.
There are five changes to Worcester's starting line-up, following their bonus point win over Scarlets at Sixways.
Nigel Redman, assistant coach, makes four changes in the pack with a new-look front row of Ollie Hayes, Ceri Jones and Rob O'Donnell, making his first start for Warriors since a summer move from Rotherham Titans.
Errie Claassens is the only change to the back division as he returns at full back with lock Craig Gillies named in the second row alongside captain Dean Schofield.
