GAVIN GUNNING, the Dundee United defender, has been struck by injury again.

The 23-year-old now has problem with his knee, after undergoing a scan on his hamstring last week and finally being cleared to return to action.

He is now a doubt for Saturday's SPFL away trip to Partick Thistle, after suffering a freak injury in training. "Gavin blocked a shot in training and just felt something," said Jackie McNamara, his manager.

"It's frustrating for everyone because Gavin is an important player and it's been a stop-start season for him."
