Leinster have fitness concerns over Richardt Strauss, Luke Fitzgerald and Mike McCarthy ahead of this weekend's Rabo Pro-12 semi-final against Ulster.

Strauss appears to be out of contention after suffering a hamstring injury during last weekend's win over Edinburgh at the RDS, while Fitzgerald's ongoing battle with a groin injury means that he is also still out of contention this week.

McCarthy's recovery from a calf strain will be monitored throughout the week.
