Kilmarnock came from behind to beat Celtic 2-1 at the BBSP Stadium, Rugby Park this afternoon and move up to fifth place in the cinch Premiership table.
Matt O'Riley gave the league leaders a first-half lead but Killie equalised through a Nat Phillips own goal in 75 minutes and Matty Kennedy grabbed a late winner.
It was a second victory of the season for Derek McInnes' team against Brendan Rodgers' side, with Kilmarnock having also won a Viaplay Cup tie back in August.
