CELTIC have been dealt an injury blow with Callum McGregor forced off against RB Leipzig.

The Parkhead skipper couldn't continue in the first-half in Germany after a knock.

McGregor looked to have suffered an injury in a challenge in the build-up to Leipzig's opener.

The everpresent Celtic midfielder had tried to tackle Andre Silva as he broke to assist Christian Nkunku's opener.

But McGregor couldn't stop the first goal and was left with an injury problem.

Having first tried to continue, McGregor was forced off through the injury after 37 minutes.

Oliver Abildgaard replaced the Celtic captain in the midfield.
