Johnny Sexton will play his first game since April when he leads Leinster out in tomorrow evening's pre-season friendly with Harlequins at the Aviva Stadium.

The 36-year-old starts at out-half against the Premiership champions, with head coach Leo Cullen naming a squad mixed with youth and experience.

Tomorrow's friendly at the Aviva will be Sexton's first game since suffering a head injury in Leinster's Heineken Champions Cup quarter-final clash with Exeter in April, before being stood down for the remainder of the season.

Sexton links up with Luke McGrath in an experienced half-back partnership, which is sure to please the large crowd that's expected to attend, with capacity at the Lansdowne Road stadium set to 15,000.

There are also welcome returns from injury for both Max Deegan and Conor O'Brien. Deegan starts at number 8 following almost a year out with a knee injury, while inside centre O'Brien has been sidelined since February 2020 with successive hamstring and knee injuries.

New signing Michael Ala'alatoa packs down at tighthead for his first game in a Leinster shirt since joining from Super Rugby's Crusaders, and is joined in the front row by Peter Dooley and Dan Sheehan.

Three academy players will be getting their first taste of senior rugby, with Wexford's Brian Deeny included alongside Devin Toner at lock, while new academy recruits Rob Russell and Chris Cosgrave start in the back three.

Included on Cullen's replacement bench are Cian Healy, Sean Cronin, Ryan Baird and Ross Byrne.
