Leeds United manager Simon Grayson is awaiting the results of captain Frazer Richardson's thigh injury picked up at the weekend.
Richardson was forced out of Saturday's win at Brighton to be replaced by Andrew Hughes. However, Grayson is hopeful that the injury is not serious.
He said: "As he was running back he pulled it. Hopefully he won't be too long.
"I thought he did well again, but Hughesy dropped in and did well. Hopefully it will settle down and we'll see how he is."
Leeds are also hoping to be able to call upon Robert Snodgrass and Jermaine Beckford for Saturday's game at home to Peterborough United.
Snodgrass injured his foot in training last week, while Beckford is building up his fitness following a hamstring strain.
