JOHNNY SEXTON WILL captain Leinster in their top-of-Conference clash with Ulster at the RDS tomorrow [KO 7.35pm; Live on eir Sport]. 

Sexton was withdrawn from last weekend’s defeat to Connacht for a Head Injury Assessment, but the Irish captain has completed the return-to-play protocols and is fit to start. He is one of a number of Leinster’s Irish internationals to return to the starting line-up. 

Jordan Larmour is fit again after a shoulder injury, and has been selected on the right wing with Hugo Keenan picked at full-back. 

Ross Byrne, meanwhile, will line out at inside-centre for the first time in his Leinster career. He will be partnered in midfield by Robbie Henshaw. 

Cian Healy starts at loosehead prop with Andrew Porter at tighthead, while Seán Cronin makes his first start of the season at hooker after recovering from a thumb injury. 

Former Australian international Scott Fardy is joined by James Ryan in the second row while, in the back row, fit-again Rhys Ruddock starts with Josh van der Flier at openside and Caelan Doris at number eight.

Ulster, meanwhile, are without the injured Jacob Stockdale. He is replaced by Michael Lowry, with the remaining five changes to the side that beat Munster last weekend all coming in the pack. 

Marcell Coetzee returns to an entirely changed back row along with Greg Jones and Jordi Murphy with Andrew Warwick replacing Eric O’Sullivan at loosehead prop. Alan O’Connor, meanwhile, replaces Kieran Treadwell at second row. 

Tomorrow’s game sees the top two sides in Conference A square off, with Ulster 10 points clear of Leinster, albeit having played two games more.
