Cork fire three goals to stun sloppy Donegal in thriller 

The result at Páirc Uí Rinn blows the group wide open.

REBEL YELL: Cork's Rory Maguire scores a goal

Cork 3-9 Donegal 0-16 

Loose. Careless. Open. None of the three were applicable to Donegal during the 12-game unbeaten run they carried south to Leeside. Looseness, carelessness, and openness condemned Donegal to their first competitive defeat of Jim McGuinness’ second coming.
