The United Rugby Championship kicks off this Friday with Glasgow Warriors facing Cardiff, and the Ospreys taking on Munster. Franco Smith's Glasgow side, featuring four changes, welcomes back several internationals. Johnny Matthews, leading in try-scoring, anchors the front-row alongside Nathan McBeth and Lucio Sordoni. Duncan Munn eyes his professional debut. Euan Ferrie, Matt Fagerson, and Jack Dempsey complete the back-row. The Ospreys see Owen Watkin return, while George North is sidelined due to injury.

Munster, led by Joey Carbery, makes three changes to face the Ospreys. Mike Haley celebrates his 100th start.
