Davis pondering options
Crewe boss Steve Davis has a selection dilemma for Peterborough's trip to Gresty Road.
Ajay Leitch-Smith, Vadaine Oliver and Lee Molyneux impressed Davis when they came off the bench during the 1-0 win over Accrington and the manager must decide whether to keep faith in his starting XI or shuffle his pack.
Defender Gregor Robertson made his first start since March on Tuesday following an Achilles injury and he will do battle with Matt Tootle and Kelvin Mellor for a starting berth at full-back.
Byron Moore remains out with a thigh injury, while Mathias Pogba (knee) is still sidelined.
Darren Ferguson will make some changes to his Peterborough team when they travel to Crewe.
The Posh boss saw his side's 100 per cent start to the season brought to a halt last weekend with a 2-0 home defeat to Crawley in a game where he thought his players "lacked energy and tempo".
Full-back Mark Little and midfielder Jack Payne are likely to be recalled to the starting line-up by Ferguson, who is expected to step up his search for a new striker when the window for loan signings opens next week.
Skipper Tommy Rowe has a slight ankle problem and is a doubt for Saturday but midfielder Joe Newell is now fit and available after a hand injury.
