Following Saturday's draw with Bradford City, which put the Blades on the brink of securing a play-off spot in Sky Bet League One, Nigel Clough revealed he has injury concerns about Terry Kennedy and Matt Done.
Kennedy limped off at half-time against the Bantams after aggravating his troublesome knee problem that has affected him throughout the season, whilst Done needs intensive treatment on his groin prior to any potential extension to the season.
Clough remarked: "Terry is struggling with his knee again and I would think he won't play in the last two matches, we need to look after players now with the play-offs in mind. Hopefully with a combination of rest and treatment he will be available for the first-leg of any play-off tie.
"Matty is struggling with his groin and ideally he needs an injection which would rule him out for around 10 days, so the sooner the better in terms of him having that treatment."
United's top six spot could be sealed on Tuesday night, without kicking a ball, should Rochdale fail to beat Leyton Orient, but the Blades boss insists the focus is on his own team, not the results of others.
Clough also suggested that he hopes to give some of his youngsters some game time before the end of the campaign.
He finished: "We know what the situation is elsewhere but we have to take care of our own business, first and foremost. Che Adams impressed when he came on against Bradford and hopefully we can get him some more action in the next few weeks. Harrison McGahey and Louis Reed are both fit and available too."
