CELTIC suffered an injury blow as Anthony Ralston was forced off injured against Hearts.

The full-back had enjoyed a bright start to the Scottish Premiership clash before hobbling off after just 37 minutes.

Ralston was caught on his ankle in the opening stages by Barrie McKay but appeared to shake off the knock.

He went on to provide an excellent whipped delivery to assist Kyogo Furuhashi's opening goal for Celtic.

But shortly after Ralston was down on the turf requiring treatment from the Celtic media team.

Ralston would then leave the park as he couldn't continue after what appeared to be a leg knock.

Fortunately, the defender was fit enough to walk off the pitch himself without the need of a stretcher.

He was replaced by youngster Adam Montgomery who went in at left-back with Josip Juranovic moving over to the right.
