URC team news: Lowe returns from injury as Marmion joins Connacht 200 club

Leinster and Ireland have been handed a timely boost with James Lowe set to return this weekend.

The winger missed the opening two rounds of the Six Nations due to a hamstring injury, and will make his comeback from the bench in tomorrow's United Rugby Championship meeting with Ospreys at the RDS (live on RTÉ2).

Head coach Leo Cullen made six changes from the side that defeated Edinburgh last week.

Cian Healy, Ryan Baird and Jordan Larmour all start having been released from Ireland camp.

Healy comes in for Ed Byrne at loosehead, alongside James Tracy and Michael Ala'alatoa in the front row.

Baird partners Ross Molony at lock, replacing Josh Murphy, while Martin Moloney continues at flanker following his fine performance last week, alongside Scott Penny and tryscorer Max Deegan.

Luke McGrath captains the side on his return with Nick McCarthy dropping to the bench, joining Ross Byrne in the half backs.

Harry Byrne slots in at centre following Ciaran Frawley's facial injury, while Jamie Osborne moves from full-back to the 13 jersey.

Jimmy O'Brien returns from injury, in between Dave Kearney and Larmour in the back three.

Among those on the bench, Sean Cronin is in line to make his 200th appearance for the province.

Leinster: Jimmy O'Brien; Jordan Larmour, Jamie Osborne, Harry Byrne, Dave Kearney; Ross Byrne, Luke McGrath (capt); Cian Healy, James Tracy, Michael Ala'alatoa; Ross Molony, Ryan Baird; Martin Moloney, Scott Penny, Max Deegan
