Nathaniel Knight-Percival and Mark Halstead return to boost Shrewsbury
Shrewsbury could welcome back Nathaniel Knight-Percival and goalkeeper Mark Halstead from suspension.
The pair missed Saturday's 1-1 draw with Bradford as defender Knight-Percival served the final game of a three-match ban, while Halstead was out following his red card in this month's defeat at Millwall.
Matt Tootle is available after sitting the last two weeks out with concussion, but Mickey Demetriou is out for the rest of the season with a knee injury.
Shrewsbury are just a point above the relegation zone and have not won in their last six games.
Sheffield United boss Nigel Adkins could field the same starting line-up for the fourth straight game.
Adkins has no new injury or suspension concerns as his side bid to extend their unbeaten run to four matches.
Ryan Flynn was withdrawn from Saturday's 3-0 win at Chesterfield as he was feeling unwell, but Adkins expects the midfielder to be in contention.
Defender John Brayford remains sidelined due to a calf injury sustained at the end of last month that may have ended his season early.
