The Sky Blues might also see Reda Johnson and Lee Burge return to the starting line-up for Millwall...
Coventry City manager Tony Mowbray confirmed Jordan Willis returned to training following a minor concussion against Wigan.
The City defender suffered a concussion in the first-half of the Wigan Athletic game and he was taken off during half-time at the Ricoh Arena.
Willis sat out the Capital One Cup game against Rochdale but has returned to training and could be in the squad for the trip to Millwall.
Mowbray also confirmed Reda Johnson and Lee Burge could return for Saturday's game at the New Den.
The City boss said: "Jordan has come back into training now and he looks ok. With head injuries, we always have to err on the side of caution.
"Reda and Lee could come back into it but Aaron and Reice did well on Tuesday night so we'll have to look at it.
"Conor Thomas has come back into training but has picked up a slight groin injury because of over-work so we might be looking at Tuesday night for him."
