Richard Thornton’s St Eunan’s were on their way to victory when the game was tied up in controversial circumstances as Leo McLoone batted home. The Letterkenny side contested that Shaun Patton, their goalkeeper, had been fouled, but the goal stood.
From way out close to the sideline, Thompson - who has been nursing an injury and was only introduced as a substitute - arched over the winner.
