The FA have released the following statement:
"Leyton Orient’s Liam Kelly has been suspended for six matches with immediate effect following the game at Plymouth Argyle on February 14 2017.
It was alleged he committed an act of violent conduct in the 86th minute which was not seen by the match officials but caught on video, contrary to FA Rule E3.
Furthermore, The FA claimed that the standard punishment for the offence would be clearly insufficient.
The player denied both the charge and the claim, however, following an Independent Regulatory Commission hearing on Friday evening [February 17 2017], the case in respect of the charge of violent conduct was found proven.
Furthermore, the Regulatory Commission considered the standard penalty to be insufficient and ordered he serve an additional three match suspension, resulting in six matches in total."
