Celtic have lost their appeal against midfielder Scott Brown's sending-off during their 1-0 defeat by Rangers.
The Hoops skipper tangled with Rangers striker Kyle Lafferty in the 66th minute of a typically heated affair between the two clubs in the Old Firm derby at Ibrox.
Many of the Celtic party were left bemused by referee Dougie McDonald's decision to send off Brown, who scored the winning goal in Scotland's 1-0 victory on Wednesday night against the Czech Republic at Hampden Park.
It will not come as good news for the Bhoys as they saw their bitter rivals take a 10-point lead with a game in hand to put the Clydesdale Bank Premier League almost out of reach.
Brown and Lafferty appeared to clash in a scuffle which ended with Lafferty falling to the floor. McDonald issued a straight red card to the Celtic player and has backed his original decision despite being asked to reconsider.
Brown will now begin a three-match ban, starting with the club's trip to Falkirk on Sunday.
AmazementCeltic later reacted with "amazement" that McDonald's decision had not been
referred to a review panel.
A club spokesperson: "We are amazed at this decision and believe it is the wrong one.
"Given the general consensus that the initial decision was incorrect and the availability of supporting video evidence, at the very least, the incident should have been referred to a separate review panel.
"Naturally, we are very disappointed that this simple opportunity was not taken.
"Clearly, it is also very disappointing that Scottish Football Association rules do not permit this decision to be appealed."
