Coventry are boosted by the return of Marlon King for the visit of Crystal Palace while Keiren Westwood is expected to shrug off a minor calf problem.
King missed last weekend`s 1-0 defeat at Leeds through flu but is now back in training.
Westwood, meanwhile, missed the chance to come on for the Republic of Ireland in midweek due to a sore calf but should be okay.
Skipper Lee Carsley (Achilles and hernia surgery) and centre-back Ben Turner (knee) are back in training but Saturday is likely to come just too soon.
Midfielder Sammy Clingan withdrew from international duty with Northern Ireland in midweek due to his troublesome knee injury and is not expected to be fit.
Nathan Cameron, Jordan Clarke and Freddy Eastwood all featured for their respective nations and came through unscathed.
Central defender James McPake remains sidelined for the foreseeable future with his lower back complaint.
Nathaniel Clyne and Neil Danns are likely to miss out for Palace.
Right-back Clyne was this week ruled out of the England Under-20 clash with France due to a knee injury and is set to lose his ever-present record this season.
Midfielder Danns is still struggling with the back problem which sidelined him for last Saturday's win over Middlesbrough and manager Dougie Freedman rates him doubtful.
David Wright, who moved into the midfield in Danns' absence, could now drop back into the defence to fill in for Clyne.
Striker James Vaughan will lead the line again after playing an hour for England's Under-21s in midweek.
Full-back Lee Hills remains a long-term absentee with a knee injury.
