Chris Wilder’s side have extended Manchester United keeper Dean Henderson’s loan at the club until the end of the season.
Dean Henderson was among the Blades squad that secured promotion last season.Sheffield United are eighth in the Premier League with seven games left of this campaign.
Meanwhile, Manchester United midfielder Angel Gomes is likely to leave the club when his contract expires on 30 June, says manager Ole Gunnar Solskjaer.
Talks over a new deal have been taking place and Solskjaer said last week he was optimistic terms would be agreed.
However, there has been no progress with Gomes, 19, over the weekend.
“I have not heard anything last night or this morning,” said Solskjaer on Monday. “If that is still the case, the answer is short: yes [he will leave].”
