Coventry manager Steven Pressley will once again be without Cyrus Christie for the clash with league leaders Leyton Orient.
The defender missed his side's last two outings with an ankle injury and is expected to remain sidelined for the next few weeks.
Forward Billy Daniels needs a hernia operation but does not require surgery immediately and could play some part.
Young defender Aaron Phillips could make his first start for the club after coming off the bench to score in Saturday's 1-1 draw with Wolves.
Leyton Orient boss Russell Slade will have an unchanged squad for their third meeting with Coventry this season.
Defender Elliot Omozusi overcame a groin problem to play at Tranmere on Saturday and came through unscathed so he will be involved again, while boss Russell Slade reported no new injury concerns following the leaders' impressive 4-0 win.
Shaun Batt grabbed his seventh goal of the season as a substitute but will find himself on the bench again unless Slade decides to give veteran striker Kevin Lisbie - whose double took his tally for the campaign to 11 - a rest.
The O's have already beaten Coventry twice this term, in the Capital One Cup in August and on penalties in the Johnstone's Paint Trophy a fortnight ago.
