Connacht captain Jarrad Butler has returned from injury to take his place in the starting team to face Ulster on Friday night at Kingspan Stadium.
Butler is one of four changes to the Connacht side that started against Leinster last weekend.
Academy player Paul Boyle also comes into the back row where he is named at number 8.
There is one change in the front row as Tom McCartney starts at hooker in place of the injured Dave Heffernan who captained the team against Leinster.
Connacht head coach Andy Friend said both sides have a challenge after a six-day turnaround from respective interpros last weekend.
“Both sides had tough games last weekend, us against Leinster and Ulster against Munster,” said Friend.
“Both sides will be trying to recover from the six day turnaround and that is the challenge in these big games.
“This week involved reviewing the game last week and fine tuning things from last weekend so we are ready to go for Friday.”
Connacht have not won in Belfast since November 1960.
