McMahon back for Blackpool
Full-back Tony McMahon returns from suspension for a Blackpool team hoping to end an 18-game winless streak when they host Millwall.
McMahon has sat out the Seasiders' last two games after picking up 10 yellow cards this season and could come straight into a team now flirting with relegation having not won since November 30.
Caretaker boss Barry Ferguson must be without on-loan defender Jack Robinson, though, as he completes a three-match ban.
All of Blackpool's squad trained on Monday, although a return for attacking midfielder Tom Barkhuizen, who recently broke his collarbone, is still a couple of weeks away.
Millwall boss Ian Holloway has five new injury worries ahead of the trip to his old club.
Saturday's surprise 1-0 win at Derby came at a cost with DJ Campbell, Danny Shittu, Scott Malone, Shane Lowry and David Forde all picking up knocks.
Striker Campbell's hamstring injury will keep him out while defender Shittu also looks set to be sidelined for a couple of weeks with a groin problem.
Defensive duo Malone (leg) and Lowry (foot) are major doubts while goalkeeper Forde (finger) will be assessed. Striker Jermaine Easter remains sidelined with a thigh injury.
