Preston North End forward Milutin Osmajic could face a lengthy ban after allegedly biting Owen Beck during their Lancashire derby against Blackburn Rovers.
Beck, on loan from Liverpool, was sent off in the 89th minute of the 0-0 draw at Deepdale after kicking out at Preston’s Duane Holmes.
After the melee which followed, Beck furiously protested to referee Matthew Donohue that he had been bitten by Osmajic, who was given a yellow card.
Television replays appeared to show Osmajic, 25, biting the 22-year-old on his upper back.
Blackburn manager John Eustace told BBC Radio Lancashire: “Owen’s got a big bite mark on the back of his neck and it’s a shame the referee didn’t see that.”
Luis Suarez, then of Liverpool, received a 10-match ban in 2013 for biting Chelsea’s Branislav Ivanovic.
