Gaelic Football's Ulster Schools Faul Cup semi-final between St. Catherine's Vocational, Killybegs and Colásite na Carraige of Carrick was halted at Fintra on Thursday.
The all-Donegal semi-final was just five minutes old when a St. Catherine's player suffered a head injury.
It is understood the player is recovering well and was brought to Sligo University Hospital as a precaution.
The match will be re-arranged for a later date.
