Donegal Celtic 0-1 Coleraine
Curtis Allen struck with 15 minutes left to give the Bannsiders a Carling Premiership victory at Suffolk Road.
The visitors dominated the first half and Ryan McIlmoyle saw his shot saved by keeper Robert Robinson while Ryan Henderson went close for DC.
Coleraine's Aaron Canning was sent-off for two yellows on 49 before DC's Darren Murray received a straight red on 66 after an off-the-ball incident.
Allen burst through before firing past Robinson for the only goal.
