David Young has made six changes for this weekend's crunch EDF Energy Cup match against the Leicester Tigers at the Arms Park.
In the backs, Jamie Roberts and Richard Mustoe, return to the starting line up. While in the back row, Robin Sowden Taylor comes in at Openside, with Martyn Williams moving down to the bench.
There is also a new front row with Taufa'ao Filise, Gareth Williams and John Yapp all starting.
Meanwhile, Seru Rabeni will make his first start of the season for Leicester Tigers
The Fijian, who returned from suspension to appear as a second-half replacement in last weekend's nine-try win over Benetton Treviso in the Heineken Cup, is named on the wing by head coach Heyneke Meyer.
Johne Murphy, who scored a hat-trick of tries in Italy last Saturday, moves to full-back, while Derick Hougaard returns at fly-half and Toby Flood moves to inside centre.
George Chuter and Boris Stankovich return to the front row and Richard Blaze is named in the second row as Ben Kay moves to the replacements' bench.
"We made a good start to the competition with the away win against Bath," said Meyer. "Now we have another tough game."
