Sheffield United confident that Dean Henderson will sign extension
Henderson's season-long deal is due to expire on June 30, with any extension for him to remain at Bramall Lane for the rest of the 2019-20 campaign needing to be finalised by Tuesday for the Cumbrian to stay put until the Blades fulfil their seasonal commitments in the Premier League at Southampton on July 26.
Under the terms of his loan, Henderson is ineligible to play against his parent club at Old Trafford on Wednesday evening, with Simon Moore or Michael Verrips to replace him.
Wilder said: "The loan is just at discussion level at an administration level. I’ve had a chat with the manager (Solksjaer) and he was fine with Dean extending his loan for the rest of the season and I appreciate Ole's help on that one.
"He's (Henderson) been great for us and we have been great for Dean. Hopefully that will get signed off before the deadline."
The Blades have selection issues for the trip across the Pennines, with John Egan suspended after receiving two bookings in Sunday's 3-0 defeat at Newcastle United.
Fellow defender Jack O'Connell has also missed the Blades' last two matches after suffering an injury in training after colliding with Henderson, but Wilder is quick to dispel some rumours doing the rounds that have suggested that he could be missing for the rest of the season.
The influential centre-half is progressing well according to Wilder.
The Blades chief remains hopeful that Phil Jagielka, who picked up an slight ankle issue in training on Saturday, will be available for Wednesday's game.
He added: "Obviously we have another 24 hours to improve Jags. He could only have come on in the last 10 minutes (at Newcastle).
"It shows you what a man and type of player he is, that he entertained it. A lot of modern players wouldn’t have done.
"We put him there because we thought they might bring Andy Carroll on if they were chasing a goal or a win. And Jags was happy to do it. He blocked a shot on Saturday and just turned his ankle."
On the condition of O'Connell, Wilder continued: "It’s a daily thing, a daily conversation I have with the medical department - who is ready and who will soon be back.
"As was said by somebody who wasn’t in the know, he’s not out for the season. I’m not going to put it out, obviously, when he’s going to come back.
"But we’re hopeful he’s going to be close. He’s a big player for us and has been.
"You don’t really want to change what has been a settled back three or five. But we’ll see how it goes. Jack, like Phil, is a warrior. He’s not missed many games in his time here and he puts everything on the line."
