The Posh boss Darren Ferguson is keen to strengthen his squad in readiness for life at the higher level, but wants to offload a section of his current roll-call first.
Goalkeepers Mark Tyler and Shwan Jalal, defenders Adam Smith, Adam Newton and Daniel Blanchett, midfielder Josh Low and striker Danny Crow have all been made available for transfer.
"We need to get players out of the club before more can arrive so the seven names have been circulated to other clubs. They are all available for transfer," director of football Barry Fry told the club's official website.
