Mayo fans were left fuming after Jordan Flynn's first-half goal was disallowed because of a little-known rule.
Flynn battled through a number of Dublin footballers and silenced Hill 16 as he rifled the ball into the back of the net late in the first half but saw his effort disallowed by referee David Gough.
The Crossmolina man picked the ball up from the ground with his knees and in a little-known rule it was disallowed.
