Tyrone attacking ace Darragh Canavan has suffered a broken wrist and could miss the All-Ireland U20 Championship semi-final against Dublin.
He has been ruled out of Errigal Ciarán's club championship campaign, which begins next weekend with a first round tie against Pomeroy.
Canavan, a son of All-Ireland winning captain Peter, is also a member of the Red Hand senior squad, and news of his injury is the latest blow to manager Mickey Harte as he prepares for the resumption of the inter-county season in October.
A number of players, including Frank Burns, Ronan O'Neill and Pádraig Hampsey, suffered hamstring injuries in club games over the past two weekends.
Canavan's wrist fracture was sustained during a training session with Errigal Ciarán. He has been in outstanding form during the opening two rounds of league fixtures.
Tyrone U20 manager Paul Devlin is hoping to have his key forward fit again by the time they meet Dublin in the All-Ireland semi-final in mid-October, but warned that such injuries can often involve complications.
