Mike Brown, Seb Stegmann and Sam Smith continue to form a prolific back three. Matt Hopper will be partnered at centre by Tom Casson with Jordan Turner Hall recovering from the cheek injury he sustained last week. Turner-Hall is expected to be out for four weeks. Nick Evans continues at fly half outside Danny Care.

Joe Gray comes back into the starting line up rotating with Chris Brooker who drops to the bench. Joe Marler and James Johnston complete the front row. Tomas Vallejos is partnered in the second row by Charlie Matthews who replaces George Robson who has a sore calf. The back row sees captain Chris Robshaw move to number 8 in place of Nick Easter who was injured at the weekend, with Luke Wallace starting at no. 7 alongside Mo Fa'asavalu at no. 6. Other injuries at number 8 at the club include Tom Guest, who has now returned to full training and Chris York, who is still some way off returning.

The bench sees Mark Lambert continue his return from injury alongside Kyle Sinckler; who replaces Tim Fairbrother who is still struggling with a hamstring injury, as front row replacements. Pete Browne comes onto the bench after his first outing of the season at Exeter on Monday evening covering the back five of the scrum alongside Will Skinner. Ugo Monye comes back from his injury sustained against Worcester in Round four of the Aviva Premiership and is on the bench covering the outside backs with Richard Bolt and Benjamin Urdapilleta covering at no. 9 & 10, with Rory Clegg rested following a knock picked up in the Monday night "A" League game.
