Offaly captain Kevin Brady has emerged as a doubt for the Faithful County's clash with Kilkenny in the Leinster hurling semi-finals on Sunday.
The Coolderry half-back is a major doubt for the game after picking up a hamstring strain while playing for his club at the weekend.
Ger Healion is also struggling to recover from a hand injury.
The Cats, meanwhile, have injury worries themselves, with Henry Shefflin, James Ryall and John Tennyson all definitely out of the match.
Full-back Noel Hickey and attacker Richie Power are also struggling with a groin strain and a hamstring injury respectively, while PJ Delaney was forced to sit out training over the weekend and a shoulder injury may keep corner-forward Aidan Fogarty out of the game.
