Posh boss Darren Ferguson will choose from an unchanged squad.
Ferguson has named the same starting XI for the last two matches and Posh have moved within a whisker of the Championship play-off places following victories against Bristol City and Cardiff.
Ferguson must decide whether to stick with his winning formula or freshen things up for Saturday's noon kick-off.
Paul Taylor could be one player to force his way into Ferguson's thinking after climbing off the bench to score the winning goal in injury time against Cardiff on Tuesday night.
Fellow forward David Ball, midfielders Ryan Tunnicliffe and Daniel Kearns and defender Josh Thompson are also options for Ferguson.
Peterborough will temporarily go second in the table with victory.
Leeds will be without first-choice goalkeeper Andy Lonergan for at least six weeks so Paul Rachubka will continue.
Lonergan fractured a finger in the recent win at Doncaster and will be sidelined for at least six weeks following surgery.
Rachubka made his first league start for Leeds in the midweek home draw with Coventry and will be anxious to make up for his stoppage-time fumble, which gifted Coventry their equaliser.
Manager Simon Grayson will name teenage goalkeeper Alex Cairns on the substitutes' bench again.
Grayson has no other new injury or suspension problems and is not expected to make any further changes as Leeds look to extend their unbeaten league run to seven matches.
Strikers Luciano Becchio and Mikael Forssell and midfielder Mika Vayrynen all made late appearances off the bench against Coventry and are expected to be named among the substitutes' again.
