URC team news: Munster suffer Antoine Frisch scare ahead of Sharks clash as Duane Vermeulen captains Ulster

The French-born, Irish-qualified midfielder has been an ever-present for the Reds in their big games this season and there will be concern about his absence given the importance of this game in the context of Munster's hunt for a home United Rugby Championship quarter-final.

Peter O'Mahony and Conor Murray sit this one out after their Grand Slam exertions, but Jack Crowley is back to play at inside centre, while Ireland squad members Roman Salanoa, Gavin Coombes and Craig Casey are back on board.

RG Snyman is once again named on the bench as Munster ease him back after his lengthy absence with a knee injury, while Simon Zebo is also named as a replacement.

Munster can leap-frog the Scots into fourth with a win in their final home game of the regular season, before they close out their season with two games in South Africa.

Glasgow are less worried about Europe given they're in the Challenge Cup, so coach Franco Smith has recalled a number of Scotland internationals.

“We know the size of the test that Munster will provide in front of their home supporters tomorrow night," Smith said.

“Our focus, though, is solely on ourselves – the squad has trained well all week since returning from their break, and we are focused on putting out the best version of ourselves tomorrow night.

“Competition for selection has been hard-fought, and everyone in the playing group is putting their hand up and pushing to be involved each week.”

Meanwhile, Connacht have made five changes ahead of a crucial game against Edinburgh at the Sportsground on Saturday afternoon.

Oran McNulty and Diarmuid Kilgallen come in at fullback and on the wing, while return in the pack Peter Dooley, Oisín Dowling and Jarrad Butler.
