Wilson added to Addicks ranks
Lawrie Wilson returns to the Charlton squad for the visit of Birmingham.
The right-back missed last weekend's 2-1 defeat at Wigan through suspension after he was sent off at Doncaster.
Left-back Rhoys Wiggins is a doubt with a hamstring problem and fellow defenders Chris Solly and Leon Cort remain sidelined by knee injuries.
January signing Yohann Thuram-Ulien continues in goal as Ben Hamer is still out with an ankle problem, although he could be back in time to face Sheffield Wednesday in the FA Cup next weekend.
Captain Paul Robinson returns to the fold for Birmingham's crunch trip.
The centre-back has missed the club's last two matches due to an automatic suspension having collected 10 bookings this season.
His comeback is a timely one after loan signing Tom Thorpe suffered ankle ligament damage on his Blues debut in last weekend's 3-3 draw against Derby and now faces a spell on the sidelines.
Fellow new boy Aaron Martin replaced Thorpe and will be hoping to start himself, as will striker Federico Macheda and winger Chris Burke, both having stepped off the bench and grabbed late goals to snatch a point against the Rams. Left-back Mitch Hancox (ankle) is also fit for selection.
