Portsmouth
Thomas Waddingham was close to returning after ankle surgery earlier this month and could be available for the Millwall game, offering Portsmouth another option after a long absence. Zak Swanson is also back in line to start at right-back after missing the 1-1 draw at Wolverhampton Wanderers, when Terry Devlin made his first start in the role.
Nicolas Schmid is expected to continue in goal ahead of Daniel Bielica after starting four of Portsmouth's last five matches. Marlon Pack and Ryan Kavuma-McQueen are both back in line to start after being used only as substitutes against Wolves, with Kavuma-McQueen setting up two goals in his last five appearances.
