Sammy Clingan and Michael McIndoe are early injury doubts for Coventry ahead of Sunday's trip to Leicester City.
Sky Blues boss Chris Coleman left Clingan out of their midweek defeat to Cardiff due to concerns about the midfielder's calf and he is facing a race against time to make the weekend as well.
Meanwhile, McIndoe was forced off at half-time on Tuesday after picking up a hip injury and is now receiving treatment to stand a chance of making a speedy return.
