Leinster's Magners League semi-final win over Ulster came at a cost with Brian O'Driscoll among a number of players injured in the game.
O'Driscoll was forced off by a knee injury at half-time and the knee was said to be swollen after the game.
Richardt Strauss (hip), Isaac Boss (hamstring) and Mike Ross (leg) also picked up knocks while Sean O'Brien sustained a cut above his eye.
O'Brien had to get three stitches inserted but coach Joe Schmidt is confident that the flank forward will be fit for the European decider.
Schmidt added that he was "hopeful" all the injured players would be available for the Heineken decider.
"Brian O'Driscoll, his knee was pretty functional in the changing room afterwards, but it's obviously swelling, so we're going to have to wait and see there," added Schmidt.
"Isaac Boss, he felt a twinge in his hamstring.
"He felt he could play on, but at this time of the season, especially when you've got a class player like Eoin Reddan to come on, it's easy enough to get him out there.
"Mike Ross got a bit of a stinger. We substituted him, but he could have gone back out there, so he's okay.
"Sean O'Brien came off to get three stitches just above his eye. It would take a lot more than that to keep Sean O'Brien out of the Heineken Cup final."
