The host side missed the chance to move to the Scottish Premiership summit at the expense of its opponent, which moved three points clear having played a game more. 

Celtic made the brighter start of the two teams, but  went behind just before half-time, as Claudio Braga drilled the visitor in front.

Derek McInnes's side arrived at Celtic Park on a four-game winless streak, but doubled its lead in the 64th minute with Oisin McEntee powering home a header from a corner.

Celtic pushed to get back into the game, with Reo Hatate striking the woodwork in the closing stages.

The host pulled a goal back in the third minute of stoppage time when Kieran Tierney drilled home, but it was too late to avert a third league defeat of the season.
