Wolves are to appeal against the red card given to goalkeeper Carl Ikeme in Saturday's 3-1 controversial Championship defeat at Norwich.
Ikeme, 30, was sent off after pushing Wes Hoolahan in the chest, but the club have been advised it is normally considered only a yellow-card offence.
Wolves are hoping Ikeme will be cleared to play in Saturday's FA Cup fourth-round tie against Liverpool at Anfield.

"Next week is a massive game for everyone at the club."
Norwich manager Alex Neil told BBC Sport after Saturday's game: "I don't think the goalkeeper should have responded in the manner that he did and deservedly got his red card.
