If he wants to play then there's no reason why he shouldn't. I actually hope he plays because holding him back for a final that is in 17 days is bizarre in my eyes. He'll be absolutely fine by then. And the point about getting injured? Could easily happen in training too.
If we win, the next game is scheduled 2 days before Paddy's Day, so would understand him not playing that, although he may be needed more then.
On the game itself, the forecast for tonight is awful, which could make this game a lot closer than one might think
