A goalkeeper played on for ten minutes unaware that his match had been abandoned because of thick fog.
Richard Siddall, who couldn't see beyond his penalty box, assumed all of the action was at the other end.
He only realised when a fan told him the match between his side Stocksbridge Steels, near Sheffield, and Witton Albion had been called off after 30 minutes.
Richard told the Daily Planet: "I didn't have a clue. I just stood there waiting for a player to come through the mist."
His manager Wayne Biggins, a former Sheffield Wednesday player, said: "We were in the dressing rooms but Richard thought we were still playing.
"No-one had a clue where he was until it dawned on us that he must have still been on the pitch."
