Xavier Rush has been named on the Cardiff Blues bench for the clash with Connacht.
Talismanic number eight Rush suffered a shoulder injury in pre-season and was expected to be out until at least next month.
And while Rush is back ahead of schedule, there is also returns from injury for Richie Rees and Deiniol Jones.
The Blues have made a stuttering start in the Magners League but coach Dai Young insists they are determined to bounce back from last week's 28-20 defeat at Munster.
Young said: "That was probably the best we've played all season. If we play like that week-in, week-out we'll win a lot more than we lose.
"All we can do now is build on the performance at Musgrave Park for the visit of Connacht to the Arms Park."
Wales prop Gethin Jenkins misses out with a neck injury and joins Tom James, Martyn Williams, Rhys Williams and Sam Warburton on the sidelines.
The Blues will defend an unbeaten record at the Arms Park which stretches back to January while Connacht have not won in Cardiff since 2001.
