“A goal had just gone in and Craig was going to the fella to say in no uncertain terms to get off the pitch.
“Obviously I can’t quote exactly what he said but it was like ‘Get off the pitch’. We were still in the game and it only takes a second to score a goal.
“My take is that he thought the fella might spit in his face or something.
“He came very close and moved towards him. Craig, with an open hand, just pushed the fella away.”
