After recovering from a foot injury, Ulster Rugby joint-skipper Andrew Trimble is available for selection for Friday night's Pro12 game at home to Connacht.
Prop Kyle McCall and lock Pete Browne have been ruled out meanwhile.
McCall will see a surgeon about his hamstring injury, while Browne sustained a concussion on Sunday's game.
