MK Dons are monitoring defenders Adam Chicksen and Dean Lewington ahead of the visit of relegation-haunted Scunthorpe.
Chicksen missed the midweek win over Colchester with an ankle injury and skipper Lewington was forced off early in the second half of that game after he suffered a recurrence of a knee injury that recently keep him sidelined for three weeks.
If both players miss out on Saturday, Dons boss Karl Robinson will have to shuffle his pack to find a left-back for the fixture.
Goalkeeper David Martin remains sidelined with the back injury that has kept him out for the past two months.
The Dons must win to take their faint hopes of making the play-offs to the final game of the season, but even then Robinson's side have to hope that sixth-placed Swindon do not win at home to Stevenage.
Scunthorpe will be without Akpo Sodje and Niall Canavan as they look to extend their survival hopes for another week.
Striker Sodje sustained a thigh injury in the midweek defeat at Bury, while centre-half Canavan broke his nose in two places early in the first half and has since had surgery that has cut short his season.
Sodje has started on the substitutes' bench in the last two matches, so Matt Godden is expected to continue alongside Karl Hawley up front, while Mike Grella and James Alabi also come into contention.
David Mirfin replaced Canavan in midweek and is expected to resume his partnership with skipper Paul Reid.
Winger Andy Barcham remains doubtful due to the thigh strain that has kept him out of the last two matches.
Goalkeeper Sam Slocombe, fit again after a thigh injury, is hoping to feature as fourth-bottom Scunthorpe chase victory while hoping the team immediately above them, Colchester, slip up against Shrewsbury.
