The loose-head prop, who has fought back from two horrific injuries since joining the club in 2016, is also set for a first start of the campaign having come off the bench in the previous four fixtures.
The ex-Wallingford man will be joined in the front row by captain Max Hayman and George Breese, the tight-head who gets a maiden start having joined in the summer.
Harry Stone is partnered by Willo Bicknell in the engine room as Bath loanee Tom Cowan switches from blind to open-side flank to accommodate the return of Aaron Tull.
Meanwhile, Ben Atkins completes the pack at No. 8.
Lamb returns to starting line-up
There is more continuity among the three-quarters, where the only change sees Andrew Lamb return to the starting line-up at full-back, Zach Clow switching to the left wing as Luke Graham looks to follow up his double on the other flank.
Louis Pereira remains at scrum-half with top point-scorer Mike Cooke outside him, the latter with 28 after the opening four games.
Morgan MacRae is the leading try-scorer with five so far and continues in his new role at inside centre, partnered by Sweden captain Axel Kalling-Smith who has touched down four times himself.
Having started last week, props Paddy Harris and man-of-the-match James Baker will look to make an impact from the bench, while Liam Elston is the other forwards cover capable of playing in the second or back rows.
Scrum-half Sam Boxhall, fresh from captaining the Royal Air Force in an away defeat at their French counterparts on Wednesday, is joined by fit-again Ellis Jones in providing options among the three-quarters.
Three travelling reserves are named in hooker and British Army captain Pete Austin, impressive young second row Paddy Jackson and Polish wing Tomek Pozniak.
The latter was in fine form in bagging a brace against Army Under 23s during the week.
