Jordi Murphy will miss Ulster’s Guinness Pro14 fixture against Southern Kings on Sunday.
Murphy sustained an ankle ligament injury in the victory over Edinburgh and, while there isn’t a clearer update, he will definitely miss the game in Nelson Mandela Bay Stadium.
Chris Henry incurred a calf strain in the Ulster 'A' game against Leinster and he will also miss out.
Both Peter Browne and Jack Owens sustained concussive injuries in the 'A' game and will follow return to play protocols.
Tom O’Toole, Jean Deysel, Clive Ross and Tommy O’Hagan are allavailable for selection after recovering from injury.
Alex Thompson has a calf injury and is unavailable for selection.
Rory Best (hamstring), David Busby (knee), Louis Ludik (hamstring), Luke Marshall (knee), Kyle McCall (elbow), Martin Moore (calf), Stewart Moore (knee) and Jacob Stockdale (hamstring) already form a lengthy Ulster injury list.
