Aberdeen have lost their appeal against the red card Pittodrie striker Sam Cosgrove received against Celtic at Parkhead on Saturday.

Cosgrove was ordered off by referee Euan Anderson following a challenge on Celtic defender Kristoffer Ajer in the second-half of the Ladbrokes Premiership match.

Derek McInnes, whose side lost the game 2-1, was keen to have the forward, who has scored 20 goals in all competitions this season, available for his side's home match against Livingston on Boxing Day.

However, a fast track tribunal hearing at Hampden today upheld the red card meaning the player will have to sit out the visit of Gary Holt's side and the match against Hearts at Tynecastle on Sunday.
