Leeds United defender Tom Lees was temporarily blinded in one eye in an incident in Friday's Championship draw at Brighton. The 21-year-old, who suffered the injury in the first half of the match at the Amex, is a doubt for Tuesday's trip to Burnley.
Boss Neil Warnock said: "Tom got a nasty finger in his face. He couldn't see out of one eye and it blinded him for a bit.
"He went to hospital and it's a worry for us."
