David Hibbert came through 70 minutes of the reserve defeat to Rotherham United.
Striker David Hibbert came through 70 minutes of the reserve fixture with Rotherham United at London Road on Tuesday afternoon, which the Millers won 4-2.
The front man, who completed his first 45 minutes following a long lay-off last week, was excellent against the visitors both in his hold-up play, but also in his work-rate and awareness.
However, the visitors who were also experienced, levelled with a header from a set-piece and in the second half scored twice in five minutes, the second of which was an own goal via the head of the unfortunate Jonson Clarke-Harris.
Clarke-Harris was deployed at left-back following the departure of Scott Griffiths to Plymouth Argyle and impressed, looking dangerous going forward and also producing some fine tackles in the defensive third.
Nathaniel Mendez-Laing twice went close while Lee Frecklington produced an energetic performance from midfield, and was denied twice by Warrington.
The Posh back-line was disrupted by injury in the second period when Peter Grant went off and Rotherham exposed that vulnerability late on. Mendez-Laing pulled a goal back late on with a clinical finish from close-range.
Posh: Day, Butt, Richens, Grant (sub Hendry 65min), Clarke-Harris, Frecklington, Newell, Tomlin, Swanson, Mendez-Laing, Hibbert (sub Anderson 72min). Unused subs: Wood, Coulson.
