Glasgow stand-off Duncan Weir has been ruled out for the rest of the season after suffering a leg injury during Friday's 35-17 win over Ospreys.
The Warriors clinched a top-four spot in the RaboDirect PRO12 with the five-try victory but it came at a cost with Weir carried off on a stretcher.
The 21-year-old Scotland international was kept in hospital overnight for the injury to be examined with a further update expected early next week.
Head coach Gregor Townsend said: "He'll miss the rest of the season and probably be out for the start of next season. It's a real shame for him.
"To miss out on the last couple of games will be disappointing but there will be other players there to take their opportunity and play for Duncan."
Glasgow are likely to need a win away at Connacht on May 3 to have any chance of securing a top-two spot and a home semi-final, but Townsend remains optimistic.
"Any of the teams in the last four have a chance of winning the title," he said.
"I would think we will have an away semi-final but whoever we get, we'll be playing tough opponents.
"If it's going to be Leinster or Ulster then we know what we have to do to win those games."
