Shay Logan: Aberdeen lose appeal against red card at Celtic Park
Aberdeen have lost their appeal against the red card shown to defender Shay Logan against Celtic on Sunday.
Logan, 30, was sent off after the final whistle at Celtic Park, where the Dons won 1-0.
Referee Craig Thomson took action after a coming together between Logan and Celtic's Mikael Lustig.
Logan, who has been at Pittodrie since 2014, will be suspended for Aberdeen's first Scottish Premiership game next season.
