The Football Association are investigating a video of what appears to be Cardiff defender Joe Bennett treading on injured Fulham midfielder Josh Onomah.

The unsavoury scene emerged on social media following Fulham’s 3-2 aggregate win over City which put them into Tuesday’s Championship Play Off Final.

Midfielder Onomah is pictured lying on the ground with team mate Bobby Decordova-Reid and City defender Curtis Nelson in attendance.

Bennett is then seen to walk over and appear to grind his studs into the outside of stricken Onomah’s left ankle, causing him to react in pain and roll away sharply.

The incident also sparks a minor scuffle between Decordova-Reid and Nelson.

Bennett was not punished by referee Paul Tierney but the film is now being studied by FA disciplinary chiefs who are looking into the incident.

If found guilty of violent conduct, Bennet faces a three game ban at the start of the new Championship season which is just six weeks away on September 12.
