Wasps have been boosted by the recovery from injury of Phil Vickery ahead of Saturday's Premiership final at Twickenham.However, he has come through training this week with no adverse reaction and will take his place in the line-up at rugby's HQ against Leicester.
It is a major boost for the London club, particularly having lost both Danny Cipriani and Tom Voyce to injury, and rugby director Ian McGeechan said: "I'm delighted that Phil Vickery has come through a week's training and contact to be fit for Saturday - it helps to make up for the loss of Danny Cipriani and Tom Voyce.
"We are obviously delighted to have made it to the final, particularly from such an inauspicious beginning in September and October.
"It will be a great occasion. Wasps versus Leicester is always a major encounter, but to be playing this one out in front of a record-breaking full house at Twickenham will be very exciting."
Riki Flutey will wear the number 10 shirt in the absence of Cirpriani, while Lewsey will move to the wing in place of Voyce with Mark Van Gisbergen called into the side at full-back.
Tigers prop Martin Castrogiovanni is ruled out through injury and Leicester go with the same XV that beat Gloucester in the semis.
