Jemal Johnson's loan move from Wolves to Leeds has been extended until the end of the season.
The striker joined the Yorkshire club on an initial one-month loan on 19th February and has so far made four appearances.
Johnson was due to return to Wolves this week but Mick McCarthy has agreed to let Dennis Wise keep him at Elland Road to aid Leeds in their battle against relegation.
As part of the new deal, McCarthy has insisted on a 24-hour recall clause.
Johnson was knocked out and stretchered from the field in a neck brace after colliding with Leicester goalkeeper Paul Henderson in the recent draw at The Walkers Stadium.
He was forced to miss Leeds' bottom-of-the-table clash with Southend on Saturday, which finished 1-1.
Wolves midfielder Karl Henry, meanwhile, admits he is likely to be ruled out for the rest of the season.
Henry had hoped to be back in action early next month after bruising his spleen in the recent defeat to Luton, but the injury is taking longer than expected to heal.
"I will be lucky to get back before the end of the season because it has not really improved," he said.
"I feel absolutely fine in myself and I am in no pain at all, but I have been told to have complete rest, so I cannot swim, jog or do anything.
"I would have preferred an ankle or some sort of leg injury because maybe you could play through that or have a time limit on how long you are going to be out."
