Chambers covered 7 games for City while McNaughton and Gilbert were absent but now Dave Jones has to find another full back or call up Chris Gunter.
Chris was an unused sub for Saturday's game against Burnley
"I lose James Chambers," said Dave Jones. "So I've got to try and find someone else or I throw in Chris Gunter. "I'll have no problems playing him if that's what I have to do. If it means me not having to move other players around."
City's next game is the live Sky match against Q.P.R. this Friday eveing.
