Celtic fullback Kieran Tierney's move to Arsenal is in jeopardy due to injury.

The left-back has been getting pain in his groin and stomach every time he kicks a ball.

The news, revealed by his Celtic boss Neil Lennon, could put the block on a move to the Gunners.

He said "He's still injured and he's rehabbing.

“He had a double hernia and he still has the Osteitis pubis problem so it's a slow burner that one."

Rest and a period of not kicking or running is thought to cure the problem, which effects 43 per cent of footballers.
