Chris Wilder is expecting three temporary departures from his squad before the window slams shut, but Ben Heneghan is now likely to remain part of the squad having made his debut at the weekend.
Of the ones that the manager thinks will leave, he remarked: "I expect Lavery, Carruthers and Nathan Thomas all to depart in the next two or three days, we've had interest and they are good players so we aren't surprised.
"I think all three will be playing their football elsewhere in February and beyond and it'll do all of them good.
"We're only looking at loan deals, so we'll see what happens in the summer. They'll increase their values if they play well or play themselves back into our plans for pre-season.
"The door isn't shut for them, but at the moment the pathway is because of the players that are in front of him.
"It's circumstances to why they've not been involved too much this season, but the first-team isn't somewhere we can sit back and let people get up to speed."
Of Heneghan, Wilder explained his reasoning: "We've looked at things with Ben, you're always making decisions and covering yourself dependent on certain situations.
"We've looked at Ben and what he can offer us, he can play the role as either the central defender in the three or the one on the right in a slightly different way to say a Basham, but the same applies to Jake Wright who won't bomb on like Jack O'Connell.
"So we've decided we need to cover ourselves in that area and Ben will remain with us."
