Scrum-half Jamison Gibson-Park is the main injury worry for Leinster ahead of their Champions Cup opener against Wasps on Friday night (kick-off 7.45pm).

The New Zealander rolled his ankle in the second half of the 30-22 victory over their rivals Munster at the Aviva Stadium and will be further assessed later this week.

Jack McGrath came through his return unscathed, as did Sean O'Brien in his first outing since his 40-minute run against Treviso last April.

Jordan Larmour is expected to be fit for selection after sitting out the interpro win.

Ian Nagle and Tom Daly have both resumed full training this week.

Ross Byrne, who came off with what looked like a hamstring, is reportedly fine according to management 

James Lowe has put his hand up for selection for the Pool 1 encounter with a storming two-try performance against Johann van Graan's side.

The New Zealander missed a number of European games last season, including exclusion from the Champions Cup final squad, as competition rules dictate that only two "non-European" players are permitted in the squad, with scrum-half Jamison Gibson-Park and Scott Fardy previously preferred.
