Peterborough United were responsible for arguably the upset of the Championship season so far last weekend when they toppled leaders Cardiff City 2-1 in the Welsh capital.
It was the Posh's first win in nine matches and a result that helped move them to within two points of safety.
In contrast, Saturday's visitors to London Road have been beaten just once in nine outings and they saw off Charlton Athletic 2-0 last weekend.
Peterborough are expected to name the same side that overcame Cardiff, while David Ngog could return to the Bolton starting lineup after he came off the bench to score both goals in their win over Charlton.
