In the front row, John Ryan comes in for the injured Dave Kilcoyne and James Cronin to make his first start in Europe.
Luke Fitzgerald starts at outside centre for Leinster in their clash with Harlequins tomorrow at the Aviva while Dominic Ryan, Kane Douglas, Isaac Boss and Zane Kirchner all come into the side.
There had been a doubt over Quins Prop Joe Marler but he has been named to start despite carrying an injury.
Luke Marshall has recovered from injury and has been named in the Ulster team to face Scarlets in Wales on Sunday.
Connacht coach Pat Lam has made wholesale changes for their Challenge cup meeting away to Bayonne tomorrow.
