Midfield duo Cole Skuse and Jamal Campbell-Ryce are doubtful for Bristol City as they prepare to welcome Coventry to Ashton Gate.
Both men picked up knocks in Tuesday's 0-0 draw with Middlesbrough and they had not recovered sufficiently enough to take part in Thursday's training so may miss out.
Marvin Elliott replaced Skuse at half-time at the Riverside and would be the top candidate to earn a start should the 23-year-old fail to recover.
Lee Johnson has returned from his loan spell at Derby and could be in line for an instant recall to the first team.
Boss Gary Johnson has no other injury or suspension concerns and after Tuesday's impressive response to last week's humiliation against Cardiff, he could be keen to keep changes to a minimum.
Freddy Eastwood should be fit to hand Coventry a major boost.
The Essex-born marksman is one of just two strikers left at the club after Leon Best completed a deadline-day switch to Newcastle, with Clinton Morrison the other.
Eastwood has struggled of late with a knee injury but he trained fully on Thursday and should be okay.
Whether he is included in the starting XI to face the Robins is a different matter altogether with manager Chris Coleman opting for a 4-5-1 formation in the past two games.
Midfielder Aron Gunnarsson is okay to feature despite being substituted during last weekend`s 1-1 draw against Blackpool shortly after being caught in the face by Brett Ormerod`s arm.
Returning centre-back Ben Turner has aggravated his ankle again but should return sooner rather than later, while Marcus Hall trained on Thursday and fellow full-back Jordan Clarke is also now running.
