Derry attacker Eoghan Bradley has been ruled out for the rest of the season by a serious knee injury.
He will miss Sunday's Ulster SFC final against Donegal, and the remainder of the Oak Leafers' championship campaign, after a scan revealed on Monday that he has sustained damage to cruciate and medial ligaments.
Bradley suffered the injury during an in-house training game at the weekend.
Derry will now have to field for the provincial final without their two top forwards. Bradley's older brother Paddy has also been ruled out for the season with a cruciate ligament injury.
