Muirkirk look set to face an SFA probe after their match-winner turned out to be on a list of players banned from the first round of the South Challenge Cup on Saturday.
The West of Scotland League Second Division side beat Third Division high-flyers Kello Rovers 2-1 in a hard-fought contest at Burnside Park.
But within hours of the final whistle, it emerged that Muirkirk's Dillan Duddy was due to serve a one-match ban after being red-carded for Carluke Rovers in their 6-1 defeat to Cambuslang Rangers in the first round of last season's competition.
