Ulster will not know the full extent of Stuart McCloskey's shoulder injury until next week but the Irish international centre is expected to play again this season.
The bulldozing 23-year-old sustained a knock to his AC joint in last Friday night's win over Connacht and at present is a doubt for the trip to face Zebre a week on Saturday.
The Kingspan outfit have no game this weekend due to the European quarter-finals but, with the business end of the Guinness PRO12 upon us and Ulster needing a near-perfect finish to earn a place in the play-offs, McCloskey is set to be an important contributor for the province between now and mid-May should his fitness allow.
There is said to be no issue with Luke Marshall despite his own substitution on Friday while Tommy Bowe and Louis Ludik are also nearing a return.
Director of Rugby Les Kiss said: "We've got to look and see where Stuart McCloskey is with that shoulder; hopefully he's fine.
"Tommy is working hard and he's so close but it's something we want to be smart with.
"It's a frustrating process but he's working extremely hard to get back, as is Louis Ludik."
