Osman joined Gretna from Maidenhead in 2007

Northampton Town have signed former Gretna central midfielder Abdul Osman on a two-year contract.

The 21-year-old Englishman had looked set to join Kilmarnock but failed a medical due to a back injury.

But Cobblers manager Stuart Gray says he is unconcerned by the former Maidenhead player's fitness.

"I've got every confidence that the boy will be fit and healthy and we will be pleased when he gets out on the pitch," Gray told BBC Radio Northampton.
