Ryan Christie has been sent off as Celtic lost their first Scottish Premiership game of the season 2-0 at Livingston, with Australian striker Lyndon Dykes sealing the hosts' victory.

Midfielder Christie was given a straight red card by referee Willie Collum in the 26th minute for a reckless challenge on Scott Robinson on Sunday.

Robinson fired Livi ahead two minutes after the restart and Dykes added a simple second in the 73rd minute for a shock 2-0 win, the Lions' first ever victory over Celtic.

A 1-1 draw at Hibernian last week was the first points dropped this season by the champions and they have now been overtaken by Rangers, who leapfrogged Celtic with a 5-0 hammering of Hamilton at Ibrox in the late game, with Jermaine Defoe scoring a hat-trick.
