Cormac Izuchukwu and James Hume are set to feature in Ulster’s United Rugby Championship game against Connacht at Dexcom Stadium on Saturday (17:30 GMT).
The URC fixture is the second of three games in a row against Irish provinces for Ulster, with Richie Murphy’s side coming into the game after back-to-back defeats against Cardiff and Leinster.
Ireland lock Izuchukwu has not played since early October and returns to the squad alongside Hume, who missed the interprovincial derby defeat at Aviva Stadium after scoring a try in the Challenge Cup match against Cardiff.
Nathan Doak is a doubt because of a calf injury with Rob Baloucoune (shoulder) and Stewart Moore (wrist) also injury concerns.
Charlie Irvine, who was replaced during the defeat against defending URC champions Leinster, has been ruled out with a calf problem.
Connacht will be looking to get back to winning ways themselves after losing 48-28 to Dragons in their last match.
