SCUNTHORPE United are unlikely to see much of injured striker Jordan Robertson before Christmas.

Manager Alan Knill says the 23-year-old front man will be missing for at least three or four months as a result of the broken ankle he suffered in training on Thursday morning.

Robertson, who has had surgery of the injury, was said to be 'distraught' at the amount of time he now faces on the sidelines.

He was already wearing a cast on a broken wrist he suffered in the Iron's draw at Wycombe Wanderers on the opening day of the campaign.

"He's going to be out for three or four months at least," confirmed Knill of the former Sheffield United trainee's ankle injury.

"We're all gutted for him, but we hope he has a speedy recovery."

Robertson's absence further stretches a United squad already desperately short of options up front.

Knill has confirmed he will be stepping up his search for a new striker, but concedes he will have to go with what he has already got when the Iron host Oldham Athletic on Tuesday.

"We're definitely short of options up front and with the amount of games we've got coming up, we are looking," he added.

"Obviously it came as a shock on Thursday because we weren't expecting that to happen, but we are looking.

"If I'm honest, I can't see us getting anybody in before we play Tuesday.

"But we'll keep being what we're being, aggressive and competitive and capable of grinding out some sort of result. We'll try our best to win games."
