Peterborough captain Grant McCann should be passed fit to face Charlton.
Midfielder McCann played the first half of Northern Ireland`s 3-0 Carling Nations Cup defeat to Scotland on Wednesday night and is expected to return to London Road fully fit.
Fellow midfielder Lee Frecklington is available after an ankle injury and could be included in the matchday squad.
Central defender Gabriel Zakuani dislocated a shoulder against Brentford last month but has made an astonishing recovery and could make a surprise return.
Striker Dave Hibbert also remains on the sidelines. Hibbert dislocated his knee back in November and is still not fit enough to return but David Ball will continue.
Ball made his debut after signing from Manchester City in the 4-4 draw with Southampton last week and will again be involved.
