Coventry's lengthy injury problems show no sign of easing ahead of their crucial home clash against fellow strugglers Peterborough.
The Sky Blues last tasted victory back at the end of September and have picked up four points from a possible 30 since then to slump to the fringes of the bottom three.
Victory against bottom-side Posh is a must and Coleman admits it will feel like 20 points and not three were they to do so. But if they are to triumph they will have to do it without as many as seven first-team players.
Right-back Jordan Clarke was the latest into the treatment room after sustaining a split in a knee ligament during Wednesday night's 2-0 defeat to Newcastle. He now faces around six to eight weeks on the sidelines.
Appropriately, captain Stephen Wright - the only player who returns for Chris Coleman - will slot straight in having completed his two-match suspension.
Defenders Richard Wood (ankle), Marcus Hall (calf) and Ben Turner (ankle), midfielders Isaac Osbourne (knee) and Sammy Clingan (broken toe) and substitute goalkeeper Dimi Konstantopoulos (knock) all remain on the sidelines.
Peterborough boss Mark Cooper has received a defensive boost.
Gabriel Zakuani is back in contention after recovering from a groin problem and Charlie Lee is also vying for a starting role.
Lee had been sidelined with a dead leg but returned to the bench for Tuesday night's match against relegation rivals Ipswich.
Paul Coutts is rated doubtful with a shoulder injury and could miss out.
The Posh are rooted to the foot of the table going into this weekend's match and have yet to win away from home in the league this season.
However, they can close to within two points of 20th-placed Coventry if they claim victory at the Ricoh Arena.
