LEO CULLEN HAS turned to experience for tomorrow’s United Rugby Championship quarter-final with Ulster.

The Leinster head coach has named captain James Ryan in his starting XV for the first time in a month as the Blues prepare for the Aviva Stadium showdown [KO 5pm, live on TG4 and Premier Sport].

Ulster have also been boosted by the return of Stuart McCloskey at inside centre after the 31-year-old missed last week’s match against Munster through injury.

For Cullen, Jimmy O’Brien keeps his place at full-back after a two-try display against Connacht and is joined in the back three by Jordan Larmour and James Lowe.

All set for a HUGE one tomorrow!
