Owain Fon Williams saves the day   Inverness keeper Owain Fon Williams was the reason Inverness were still interested in the game as it approached the ninety minutes and a very late Alex Fisher header earned an unlikely draw. Tom Rogic had knocked home the opener but his strike was bettered by a fantastic goal from Billy King. Sloppy play in midfield led to Scott Sinclair going it alone to put the visitors ahead before the late action around the Celtic box saw substitute Fisher level.
