OXFORD United expect to find out the extent of Dwight Tiendalli’s injury shortly.

The full back was forced off 28 minutes into the 1-1 draw at Milton Keynes Dons with a hamstring problem sustained attempting to block a cross.

It was only Tiendalli’s second game back, after two years recovering from knee and thigh problems.

United have to wait for the swelling to go down before assessing the extent of the problem, but boss Pep Clotet was disappointed to see the 31-year-old hobble off after proving his fitness.

He said: “All the tests we had with him were perfect.

“It’s not his day and I’m very sad for him, but I hope he can recover as soon as possible.

“It wasn’t like it was at the end of the game when the muscle is more vulnerable, it’s completely unfortunate.

“He managed to come back before, so he will come back from this one.”

There was better news about Curtis Nelson, who was left out to allow his jarred knee to completely settle, but is due to return this week.

Clotet also explained the decision to not play deadline day signings Alex Mowatt and John Mousinho.

He said: “We were very happy with the two players who have come to help us, but we have to respect the ones who have been working very hard in the whole week.

“They (Mowatt and Mousinho) will be involved this week and then earn their right.”
