O’Callaghan: I’m innocent
The former Cork City star, making his full debut for the Tractor Boys in the FA Cup Fifth Round tie, received a straight red in first half stoppage time from referee Steve Bennett.
O’Callaghan was adjudged to have kicked Watford centre- back Danny Shittu after the two had challenged near the touchline. The Irishman insisted there had been no intent on his part.
