Leeds defender Liam Cooper has been banned for six matches by the Football Association.
Cooper, 25, was charged with violent conduct following an incident in Leeds' 1-0 Championship defeat at Reading on Saturday.
TV footage appeared to show Cooper catching Reading substitute Reece Oxford on the side of the head as he lay on the pitch, and the FA has now acted.
Cooper served the first match of his suspension in the 2-0 loss at Brentford on Tuesday, meaning he will not be available until the last match of the regular season at Wigan.
The incident against Reading was not seen by the match officials, and while Cooper accepted the charge of violent conduct the FA felt a standard punishment would be insufficient.
A statement said: "Leeds United's Liam Cooper will serve a six-match suspension with immediate effect following an Independent Regulatory Commission hearing.
"The defender was charged with violent conduct in relation to an incident in or around the 74th minute of the game against Reading on Saturday, which was not seen by the match officials at the time but caught on video.
"Furthermore, the FA claimed the standard punishment which would otherwise apply for the misconduct committed would be 'clearly insufficient.'
"The player accepted the charge but denied the claim. However, that matter was found proven and his total suspension of six matches includes the standard one additional match for it being his second dismissal of this season."
Cooper's ban means he will miss Saturday's visit of Preston and sit out games against Newcastle, Wolves, Burton and Norwich as Leeds aim to secure a Championship playoff place.
