Rogic was felled by a sliding challenge from Darren O'Dea in the 46th minute and didn’t emerge for the second half at Celtic Park.

O'Dea received a yellow card for the rash tackle and Leigh Griffiths scored from the resulting free kick.

But it's the image of the Australian star in a moon boot that will send shivers through the ranks of Celtic and Socceroos fans.

The win puts the Hoops 11 points clear at the top of the table but coach Brendan Rodgers refused to be drawn on the extent of the ankle injury to his star midfielder only saying: "We'll assess tomorrow at training."

Rogic suffered a string of injuries early in his Celtic career but has been in red hot form this season with 10 goals and five assists.
