Ryan Christie helped Aberdeen into second place in the Premiership with a goal in the 2-0 win over Partick Thistle at Pittodrie.
Throughout the top three divisions in the SPFL Celtic players were in action as they gain valuable experience which will hopefully see them return as first team players.
Christie replaced Shay Logan in the 64th minute and scored in stoppage time as the Dons moved into second place ahead of Sevco on goal difference.
