Sutton United have accepted the resignation of reserve goalkeeper Wayne Shaw, who is under investigation for potentially breaching betting rules.
The Gambling Commission and Football Association are investigating if there was a breach of betting regulations after the 45-year-old ate a pie during Monday's FA Cup loss to Arsenal.
A bookmaker had offered odds of 8-1 that Shaw would eat a pie on camera.
"What happened didn't make us look very professional," said boss Paul Doswell.
"It's something that we've dealt with quickly as a club," he told Sky News on Monday. "Wayne himself offered his resignation to the chairman this afternoon, which has been accepted.
"It's a very sad end to what has been a very good story."
Shaw, who said he was aware of the betting promotion prior to the match, played the incident - in which he ate the pie while standing by the substitutes' bench - down as "a bit of fun".
