Celtic defender Kelvin Wilson could be set to land a two-match ban after being issued with a notice of complaint for an alleged elbow on Dundee striker John Baird.
Scottish Football Association compliance officer Vincent Lunny has charged the centre-back with violent conduct "by striking an opposing player, namely John Baird, with his elbow'' during Celtic's 2-0 Boxing Day win at Dens Park.
Wilson has until 1500 GMT on Monday to respond to the charge with a hearing pencilled in for next Thursday if he decides to challenge the ban.
Wilson is available to manager Neil Lennon, who is without injured defenders Adam Matthews and Charlie Mulgrew, for the Premier League clash against Hibernian at Easter Road.
The incident happened off the ball just before half-time in the Dens Park clash with referee Iain Brines taking no action. Baird was initially angered and needed treatment, but later accepted Wilson's explanation and did not want retrospective action.
Baird said after the game: "He has clocked me but I think it was accidental. I thought I had lost my teeth. It was an elbow but I have to stress I think it was accidental.
"I have pulled him and he is obviously getting his arm out the road. I spoke to him as I was going up the tunnel and he said, 'you were pulling me'. It's just one of those things.
"I think if someone pulled me, my first reaction is to get your arm out the road. It's not as if he has come over and said, 'here, take that'.''
Wilson would miss SPL games against Motherwell and Hearts if he accepted his ban on Monday or lost his fast-track tribunal hearing.
