The Blues centre-back has now served his three game ban for his sending off in the home draw against Ipswich last month and is likely to step straight back into the starting line-up against The Hatters..
David Dunn, who missed the home game against Leicester City with a calf injury a fortnight ago, also has an outside chance of making the squad for the match at Kenilworth Road.
Nicklas bendtner however will not be in the squad has he recovers from a knee injury sustained during Denmarks EURO 2008 qualifier against Northern Ireland last week.
