Michael Lowry is out of Ulster’s Investec Champions Cup game against Leicester on Saturday after being added to the Irish province’s lengthy injury list but Iain Henderson will be available for the Welford Road game.
Utility back Lowry suffered a thigh muscle injury in the win over Connacht on 28 December.
Hooker Rob Herring was a late withdrawal from the game in Galway after sustaining a calf injury in the warm-up and his fitness will be monitored this week.
Ireland lock Henderson will join Ethan McIlroy and Callum Reid in being available for selection after a recent absence while Stewart Moore has resumed squad training following a thigh injury.
Henderson missed the games over the Christmas period against Munster and Connacht after sustaining an injury in the Champions Cup home defeat by Bordeaux.
Ireland internationals Jacob Stockdale (hamstring), Stuart McCloskey (hamstring), Robert Baloucoune (calf), Tom Stewart (hamstring) and James Hume (knee) are among Ulster’s injury absentees with Ben Moxham (knee) and Sean Reffell (ankle) also ruled out of the Leicester contest.
Tom O’Toole will miss Saturday’s game after being handed a six-game suspension which will rule him out of Ulster’s next three matches and Ireland’s opening two Six Nations fixtures against England and Scotland.
O’Toole was red carded against Munster and served the first game of his suspension when missing the Connacht game.
