Coventry striker Gary McSheffrey will be assessed ahead of the match.
The forward strained the medial ligament in a knee at Fratton Park on Tuesday and was forced off shortly after bagging the second goal in an impressive 3-0 triumph over Portsmouth.
Should McSheffrey be passed fit to feature against the Lions, Andy Thorn could well keep faith with an unchanged matchday 18, with the Sky Blues caretaker boss having named the same set of players on the south coast as he did for last weekend's 2-2 draw at Derby.
Captain Lee Carsley remains on the sidelines with his troublesome Achilles problem, along with defenders Richard Wood (groin), Ben Turner (knee) and James McPake (back).
Coventry are aiming to make it four games unbeaten for the first time since early December.
Millwall will be without their two first-choice strikers.
Top scorer Steve Morison starts a three-match ban following his stoppage-time red card against Bristol City on Tuesday night and Kevin Lisbie has been ruled out for the season with the ankle injury he suffered three days earlier against Leeds.
Boss Kenny Jackett could turn to Josh McQuoid, who has yet to score for the Lions, and veteran Neil Harris, with three goals to his name this term, to spearhead the attack.
Winger Hameur Bouazza and youngster John Marquis provide alternatives while Liam Trotter has also played behind a lone striker this season.
Fit-again Jimmy Abdou (knee) could return to the midfield if Trotter is pushed further forward.
Defender Jack Smith (hamstring) missed out in midweek and will be checked over.
