The Black Cats will be without top scorer Ross Stewart for the rest of the season with an Achilles injury, while captain Corry Evans has also been ruled out for the remainder of the campaign.
Aji Alese, Dennis Cirkin and Alex Pritchard are doubts for the Millwall match with less serious injuries, while Luke O’Nien is suspended.
New signing Joe Gelhardt is expected to make his debut after joining the club on loan from Leeds United last week.
Here’s our predicted Sunderland line-up to face Millwall this weekend:

2. RB: Trai Hume

3. CB: Danny Batth
Batth had arguably been Sunderland’s best player this season until suffering a calf injury in December. The 32-year-old has returned to the side since and started the Black Cats’ last two fixtures. Photo: Frank Reid
4. CB: Daniel Ballard
We’re now starting to see why Sunderland paid a seven-figure fee for the 23-year-old in the summer, with Ballard proving a key player since recovering from a lengthy foot injury. Photo: Frank Reid
