Mario Lemina was sent off against Southampton for 'running aggressively at the referee', according to a report.
The midfielder was shown a second yellow on 27 minutes for reasons initially unclear, but, according to the Athletic, the card was shown by referee Jarred Gillett for the bizarre reason.
Wolves players fiercely protested the decision, but the call stood and Julen Lopetegui's side had to play over two thirds of the game with 10 men.
The sending off didn't impact them too much however, with the visitors coming from 1-0 down to secure a 2-1 win as they continue their revival under their new manager.
