Harlequins will be without two of their key players for Saturday's European Champions Cup trip to Dublin to face Leinster.

Both Nick Evans and Chris Robshaw have been ruled out of the game after suffering injuries during last weekend's Pool 2 encounter at the Twickenham Stoop.

Out-half Evans suffered a groin strain early in Sunday's game at the Stoop, while England captain Robshaw requires further assessment of a shoulder injury.

Harlequins beat Leinster 24 - 18 last weekend.
