Sheffield United are reeling from yet another injury blow with the news Jordan Stewart has suffered a season-ending knee injury.
Stewart, who has partially ruptured his cruciate ligament, is the latest in a long list of first-team squad members to sustain serious injury this season.
Defenders Gary Naysmith, Derek Geary and Ryan France have all missed most of the campaign due to knee injuries, Henri Camara (groin) and Ched Evans (broken collarbone) are unlikely to feature again this season and Jamie Ward (hamstring) and Toni Kallio (calf) are also long-term absentees.
Naysmith came through 75 minutes for the reserves unscathed in midweek but is not expected to be ready to return.
Manager Kevin Blackwell, who has no other new injury or suspension worries, could recall Glenn Little, Kyle Bartley and Mark Yeates, with all three unlucky to miss out in Monday night's defeat at Newcastle.
The Blades are chasing their first win in six matches and have only won one of their last nine in the Championship.
Chris Coleman has received mixed injury news ahead of Coventry`s trip to Bramall Lane.
On-loan striker Jonathan Stead has discovered he requires a cartilage operation while midfielder Gary Deegan must also go under the knife to repair ankle ligament damage, ending their respective seasons with four games remaining.
However, Coleman will be able to call upon the services of attacking duo Freddy Eastwood and Michael McIndoe.
Eastwood missed both of Coventry`s games over the Easter period with a back complaint while McIndoe has been sidelined with back/hip problems since the defeat to Cardiff on March 16.
City have failed to recover from that loss and have seen their play-off hopes drift away having taken two points from a possible 15 since the dramatic 2-1 reversal.
