Dublin forward David Treacy is unlikely to play again in this year's All-Ireland Championship, after picking up a hamstring injury.
The Dubs have been blighted by injuries this summer, with Tomás Brady, Conal Keaney and captain Stephen Hiney all currently sidelined by cruciate knee ligament injuries.
Just last week Treacy's Cuala club-mate Oisín Gough was ruled out of contention with a broken hand.
It is more bad luck for Treacy as he has struggled for fitness over the past two seasons. He suffered a cruciate injury last year and repetitive hamstring injuries have kept him out of the side this season.
He has been used as a substitute three times by Dublin boss Anthony Daly in the 2011 Championship, including a 38-minute run-out in the recent quarter-final win over Limerick.
