Sanchez Watt, who now plays for Hemel Hempstead in the National League South, was given his marching orders by ref Dean Hulme when the official asked him his name to book him for kicking the ball away.
However, the official grew frustrated when he thought Watt was replying by saying 'What?' multiple times - so showed him a straight red card for dissent.
Answering "Watt" three times, with each time the referee believing he had said, 'What?', the official gave the player a second yellow card for dissent.
Watt was then sent off for dissent, not having done anything wrong.
County under High Wind Advisory Monday
Temperatures should be held down by the cloud cover, but it will be windy again with gusts up to 30 miles per hour . The high winds are then expected to diminish Tuesday night when it is expected to be cool and clear.
"It was a human error", Hemel Hempstead chairman Dave Boggins told BBC Sport.
"He came into the boardroom after the game and explained how he had made the mistake".
The Tudors went on to register a 2-0 victory, with Watt getting his name on the scoresheet - though presumably that took an absolute age to get right, too.
"He was very apologetic and saw the amusing side of it", Boggins said of referee Hulme.
A former Arsenal starlet has been sent off after a referee mistook his name for an act of dissent.
