Antoni Sarcevic and Jamie Proctor are stood down from duty as Fleetwood Town face Sheffield United in the Johnstone's Paint Trophy
Dionotan Teixeira returns to the Fleetwood side - Joe Davis moving to right back with Conor McLaughlin away on international duty.
Nick Haughton replaces Sarcevic in midfield, playing alongside Jimmy Ryan and Eggert Jonsson.
Up front McManus replaces David Ball, Jamie Proctor making way for Jamille Matt as boss Steven Pressley desperately hunts for goals.
Town haven't scored in two games - drawing a blank in Saturday's FA Cup exit at the hands of Walsall.
Pressley has an aggressive bench at his disposal - with no defenders among his five substitutes.
Fleetwood: Maxwell, Davis, Pond, Teixeira, Bell, Jonsson, Ryan, Haughton, Matt, McManus, Forbes
Subs: Gogic, Sowerby, Grant, Ball, Hunter
