Saracens travel to Galway to begin their Heineken Cup campaign on Friday evening, to face Connacht at The Sportsground.
Will Fraser retains his place at openside flanker, with George Kruis continuing at lock forward as Saracens make six changes to the starting pack.
In the backs Owen Farrell returns at fly-half, with Alex Goode reverting to his more accustomed full-back role. Chris Wyles and Joel Tomkins continue to partner each other in the centres, and David Strettle returns to the left wing.
Saracens Director of Rugby Mark McCall; “We have got to be right mentally and physically. Connacht really step it up in this competition – I know that from my experiences in Ireland.
“It’s a really good, passionate atmosphere there and we have to be on our game – but having to grind out a victory against Wasps will not have done us any harm.”
“I know from experience that we have to be on the money when we go to the Sportsground” McCall added.
“I think in the last four seasons Connacht have beaten Harlequins, Biarritz and Toulouse in Galway.
“If that doesn’t focus our mind, I’m not sure what does.”
