James Hanson (calf) and Jack O'Connell (dead leg) will both undergo fitness tests ahead of Saturday's penultimate game of the season against the MK Dons.
Hanson has missed the last two games with the problem, whilst O'Connell picked up the knock in the Easter Monday victory over Bradford City at Bramall Lane.
Speaking at his pre-match presser, boss Chris Wilder was keeping his cards close to his chest in terms of other selection dilemmas, as United look to remain on course to hit 100 points with a win and extend the unbeaten run to 16 matches in the process.
Jay O'Shea, Ethan Ebanks-Landell and former Dons star Samir Carruthers will be amongst those hoping for a recall for the fixture, which will see the Champions backed by over 7,000 supporters at Stadium:mk.
Meanwhile, for the home side, boss Robbie Neilson has no fresh injury concerns and could name an unchanged starting XI following the recent 2-1 success at play-off chasing Southend.
