Aleksandar Mitrovic faces a lengthy ban for violent conduct as the Football Association will take into account his previous elbowing cases.
The Fulham striker struck Leeds centre-back Ben White after 87 seconds of his team's 3-0 defeat to their Championship promotion rivals.
He will have to wait until Monday morning for the referee's report to be lodged but Tony Harrington did not take action, leaving the Serbia international facing an investigation.
The FA will take into account his elbow on Manuel Lanzini in 2017 while at Newcastle, which was punished with retrospective action.
He was given three matches for that offence and is likely to get an increased punishment this time around. Fulham have just seven games left and Mitrovic could miss the bulk or even all of them.
His former manager at Newcastle, Steve McClaren, was working as a pundit at Elland Road and suggested the striker had not changed since his spell at St James' Park, where he also received two red cards.
