Reading captain Matt Mills returns from suspension and is set to replace Zurab Khizanishvili in Brian McDermott's starting XI.
Menahile Jimmy Kebe could make his first start since October after finally recovering from his nagging knee injury after benefiting from an extra week off.
The Royals were not in action after last weekend's trip to Sheffield United was postponed and McDermott could make a few changes.
Club captain Ivar Ingimarsson remains a long-term absentee with a hamstring problem as does central midfielder Brynjar Gunnarsson who continues to struggle with a thigh problem.
Coventry boss Aidy Boothroyd is reporting no new injury problems ahead of the game.
The Sky Blues boss remains without midfielder Sammy Clingan and centre-back Ben Turner (both knee), with the former tipped to return first over the festive period.
Full-back Stephen O'Halloran is back in training and performing well following his return from a long-term back problem, but needs to undergo the equivalent of a pre-season training regime before being considered for selection.
December 2002 was the last time the Sky Blues won four successive league matches and Boothroyd is expecting a tough test at the Madejski Stadium as his crop of 2010 look to match that record.
He said: "If you are going to be successful you've got to break records, and that's great. If we can keep a clean sheet and get anything out of the game then it will be a positive result.
"As I say, the more points we get then the better it is for us but it presents different problems - the fact people think we've arrived and are better than what we are. And we're not, we've got a long way to go. We're very much a work in progress."
