The club has won its appeal against the red card shown to Paddy McNair during the win against Huddersfield on Tuesday.
The Northern Ireland international was shown a straight red card by referee Jeremy Simpson following a challenge on Juninho Bacuna nine minutes from time.
The club immediately lodged an appeal against the card and are delighted that it was overturned at an FA hearing on Thursday.
An FA statement read:
An independent Regulatory Commission has removed Paddy McNair’s three-match suspension following a successful claim of wrongful dismissal.
The Middlesbrough FC defender was sent off for serious foul play during an EFL Championship game on Tuesday [16/2/21] against Huddersfield Town FC.
