Ian Poveda has been ruled out after suffering a hamstring injury, meaning he’s played his last game in tangerine.
Elsewhere, Jordan Thorniley, Keshi Anderson Shayne Lavery and Jerry Yates will undergo fitness tests before a decision is made over their availability.
Marvin Ekpiteta, Tom Trybull and Rob Apter also featured in an in-house game at the start of the week.
With that in mind, here’s how we think the Seasiders will line up against Gary Rowett’s side...

2. GK - Dan Grimshaw
Despite his best attempt at juggling against Birmingham, Grimmy will keep his spot after keeping two clean sheets in his last three games. Photo: CameraSport - Lee Parker
3. RB - Jordan Gabriel

4. CB - Curtis Nelson
Coming up against a physical and direct Millwall side, Nelson will need to be at his best in the centre of defence. Photo: CameraSport - Dave Howarth
5. CB - Jordan Thorniley

6. LB - Andy Lyons
Looks better suited at right-back but he's more than held his own on the left-hand side. Offers a threat going forwards as well. Photo: CameraSport - Lee Parker
