OXFORD United have announced Simon Eastwood is expected to miss at least the next couple of weeks.

The goalkeeper suffered a knee injury late in Saturday's 1-0 win at Walsall in the Emirates FA Cup.

And boss Karl Robinson has raised the potential for bringing in some short-term cover if his absence is prolonged.

While Eastwood finished the game at the weekend, the 30-year-old reported some pain and was sent for treatment.

Robinson told the club's website: "It’s a strange one really because the scan didn’t show too much damage but he is clearly in discomfort.

"So we won’t ask him to make the trip to Exeter on Wednesday and then it looks like we will need to do another scan in a week to ten days time once it settles down."

While tomorrow night's trip to Exeter City in the Leasing.com Trophy was a case for promoting Jack Stevens to play anyway, Eastwood now looks set to miss two big Sky Bet League One games.

The U's host Shrewsbury Town on Saturday and visit Milton Keynes Dons a week later.

And the timescale also raises a doubt over whether the goalkeeper would be fit to face Manchester City in the Carabao Cup quarter-final on December 17.

It could see United move for a free agent if the problem persists.

Robinson said: "We all know that Easty hates missing games but it’s a long season and we need him to be right.

"Meanwhile we have Jack Stevens who will have a chance to show that he is ready to take his opportunity.

"We will maybe look at a short term option to give us cover and competition in that position as well, once we get a clearer picture of how long Easty will be out for.”
