London Wasps boss Warren Gatland has named his side that will face the Leicester Tigers for the Zurich Premiership game at Welford Road on Saturday.
There are three changes from the side that beat the Newcastle Falcons 30-26 last weekend.
Former Wales international Rob Howley will replace Peter Richards at scrum-half and will captain the side.
Mark Lock replaces Ian Clarke at No.8, and Peter Scrivener comes in for James Haskell on the bench.
"No matter how many games the Tigers have lost, they are still a good side and we are very wary of them," said Gatland.
"They are desperate for a win and will be looking to bite back at anytime. We expect a battle but are prepared for it."
