Millwall should be unchanged after back-to-back wins.
Boss Kenny Jackett stuck with the line-up which won 3-0 Leicester last weekend when his side took on Ipswich and was rewarded with a fine 4-1 victory.
In-form strike duo Jay Simpson and Darius Henderson will start in attack again having hit six goals between them in the last two games.
Midfielder Therry Racon (ankle) and striker Josh McQuoid (illness) are fit and available after their recent lay-offs but cannot break into the squad at the moment.
John Marquis is recovering from a hernia operation and fellow forward Shaun Batt is continuing to build up his fitness following a long-term knee injury.
Chris Hussey will miss Coventry's trip to Millwall but fellow defender Richard Wood comes back into contention.
Left-back Hussey limped out of Saturday's 1-1 draw at Doncaster after 26 minutes to be replaced by James McPake, who will hope to start at The Den.
But the Scot faces competition from fit-again Wood after he sat out at the Keepmoat Stadium with a knock sustained against Burnley the week previous.
Young midfielder Gael Bigirimana serves the second game of a three-match suspension following his red card against the Clarets.
Otherwise, manager Andy Thorn has a fully-fit squad to select from with Gary McSheffrey (back) and Carl Baker (ankle) having returned against Doncaster at the weekend.
The Sky Blues, third-bottom in the Championship, travel south searching for what would be only their third win of the season but they face a tough task against a resurgent Millwall side who have won their last two, scoring seven goals in the process.
