On-loan Portsmouth striker Paul McCallum has been hit with a seven-game ban after being found guilty of improper conduct.
The 21-year-old was found to have made contact with the referee following his recent red card against Southend United.
McCallum was given an initial three-game suspension for the dismissal, but that was increased to seven matches due to his reaction.
He is currently on loan at Pompey from West Ham United until the end of the season.
