Celtic will be without right-back Cha Du-ri for longer than they anticipated with an ankle injury.

The 30-year old picked up the problem on his return from international duty with South Korea at the Asian Cup and may required surgery which will surely keep him out for the remainder of the season.

But Hoops boss Neil Lennon said even if surgery was not needed, Cha will still be sidelined for some time.

"Cha took a bad one. We are sending him to see another specialist to get another opinion," Lennon said. "We are hoping that he will not require surgery, but even if he doesn't require surgery he will be out for a significant period of time.

"He felt it in the first day of training when he came back. He seemed to jar his tendon. It was pretty innocuous really because he came through the training session okay and only really felt it afterwards."
