Celtic midfielder James Forrest will serve an automatic one-match ban after losing his appeal against the red card he picked up against Hamilton.
Forrest was shown a straight red card four minutes after the restart in the 1-1 draw on 12th January for a challenge on David Buchanan.
The Parkhead club submitted an appeal for wrongful dismissal but the Scottish Football Association's review panel dismissed the claim on Tuesday.
A statement from the SFA confirmed: "The Scottish FA Review Panel today dismissed a claim for wrongful dismissal submitted by Celtic Football Club regarding the ordering-off of their player, James Forrest, during Hamilton Academical v Celtic at New Douglas Park on January 12.
"An automatic one-match suspension will be applied, with 12 penalty points added to the player's disciplinary record."
An independent three-man panel consisting of a former referee, a former manager and a former player took the decision.
In response, a Celtic spokesperson said: "Clearly we are disappointed that our claim has not been upheld."
