The Railwaymen are looking to bounce back from consecutive defeats to the U's fellow strugglers Hartlepool and Portsmouth and Inman sustained ankle damage against the former.
"Brad is still out but he is making good progress and it is nothing too serious," Davis told his club's official website.
"He should be out for a week or so, so we'll have to see with him."
With the exception of rookie defender Jon Guthrie, who will miss the rest of the season after undergoing hernia surgery, Davis has no other injury worries as he looks to secure the victory that will take Alex to the much-desired 50-point mark.
"I've pushed them hard this season, more than I did last season and they have done superbly well so far," he added.
"But we want to push on and finish as we possibility can. The first priority is still 50 points and safety."
