Coventry will assess Carl Baker and Lukas Jutkiewicz ahead of their trip to Middlesbrough on Easter Monday.
Midfielder Baker was forced off at half-time in Good Friday's 1-1 home draw against Scunthorpe, while striker Jutkiewicz followed him off the field on the hour mark.
Speaking after the draw, caretaker-boss Andy Thorn said: "We'll assess the boys on Sunday morning before we travel up, we'll see how we are. We've got a nice squad and I'm not frightened of playing anybody.
"Bakes (Baker) and the Duke (Jutkiewicz) came off with slight little niggles, so we'll see how they are. We'll freshen things up if we need to."
Thorn continues to be without Gary McSheffrey (knee), Lee Carsley (Achilles), Ben Turner (knee) and James McPake (back) who are all unlikely to play again this season.
