Queens Park Rangers will play fellow play-off chasers in a must-win game for both sides on Tuesday evening.
The hosts currently sit in eighth, two points above the traveling side who are in ninth.
Both sides have a game in hand on sixth place Blackburn Rovers who are just one point ahead of Sheffield United but are three points ahead of the Hoops. Therefore, a win for either team would be extremely beneficial towards a promotion charge.
One of the main things letting Rangers down is their goal difference, if they are going to challenge the teams above, they will need to improve it.
The visitors have lost the last three outings with only two wins in the last 11. The Blades’ form is slightly better, picking up four victories out of the last 11 and after a 1-0 loss away to Stoke City at the weekend, they'll be looking to get back to winning ways.
Star man Chris Willock is still out after suffering a hamstring injury and won't make a return for the remainder of the campaign.
Sheffield United (3-4-2-1)
Foderingham, Robinson, Egan, Davies, Norrington-Davies, Berge, Norwood, Baldock, Gibbs-White, Ndiaye, Jebbison.
Queens Park Rangers (3-4-2-1)
Westwood, Sanderson, Dunne, Dickie, Wallace, Johansen, Field, Odubajo, Dozzell, Chair, Dykes.
Ones to watch
The 22-year-old has cemented his spot as one of the best players in the EFL since joining United on loan from Wolves in August.
He has racked up a total of nine goals and seven assists in 28 matches this season, scoring most recently in a 2-0 win over strugglers Barnsley.
Also a danger from attacking midfield, Chair has scored eight and assisted four this season.
The reverse fixture between the two sides was meant to take place on December 30 2021 but due to Covid 19 cases within QPR, it had to be postponed.
It is now set to take place at Loftus Road on April 30 2022.
The visitors haven't defeated the Sheffield side since the 31st October 2017 so will be looking to make a change.
How to watch
The game kicks off at 19:45 BST on Tuesday April 5.
It is not available to watch in the UK but overseas supporters can purchase a live stream of the game via either club website.
Audio options are also available.
