GATLIN O’Donkor is set to have a scan today after suffering an ankle injury in training.

The Oxford United striker sustained the issue last week, days after signing his first professional contract.

O’Donkor, 17, has been training with the first team and was an unused substitute at Derby County on July 30, after making his Sky Bet League One debut in the final game of last season.

U’s head coach Karl Robinson said: “It’s bad. He’ll have a scan and then we’ll have more understanding of what that is.

“He’s on crutches and we’ll see how that sits.

“It was a tackle, it’s just an ankle problem.”
