The Seasiders will be without Charlie Goode, who has returned to Brentford for scans on his hamstring injury, while the likes of Andy Lyons, Morgan Rogers and Josh Bowler will be pushing to start.
Here’s how we think Mick McCarthy’s side might line up against the Millers...
7. CM - Tom Trybull

8. CM - Kenny Dougall
Charlie Patino and Sonny Carey are also in the mix, but McCarthy might opt to go with two sitters if he plays a more attack-minded system. Photo: CameraSport - Dave Howarth
9. RW - Josh Bowler
Surely he has to start? And if so, in his favoured position too. He's a game changer. Photo: CameraSport - Dave Howarth
10. CAM - Ian Poveda
Poveda has rarely played since being praised by Mick McCarthy, but - like Bowler - he's another one that help win a game on his own. Photo: CameraSport - Dave Howarth
11. LW - Morgan Rogers
Like Bowler, Rogers was another one that helped turn things off the bench on Tuesday night. Deserves to make an impact from the start. Photo: CameraSport - Dave Howarth
12. ST - Jerry Yates
After producing a tireless display in midweek, Yates could be better served with some more creative players behind him. Photo: CameraSport - Dave Howarth
