Peter O’Mahony returns to captain Munster against Ulster tomorrow and is one of four personnel changes to the side that faced Leinster in the final regular game of the season.

A win will extend Munster’s season into the semi-final stage of the domestic tournament, while a loss will bring an end to the Van Graan era in Thomond Park.

Damian de Allende, Gavin Coombes, and Stephen Archer also start for the knock-out clash with Coombes making his first appearance since the beginning of April after overcoming an ankle injury.

It’s a landmark occasion for Stephen Archer who will make his 248th appearance in red on Friday night becoming Munster’s second most-capped player.

Jack O’Donoghue was unavailable due to a back strain, while Thomas Ahern will see game time in coming from the bench.
