Nigel Pearson's City have won their last five league games and will be aiming to win six in a row for the first time since the 1992-93 season.
Peterborough are bottom of the table after conceding a late equaliser in their 2-2 draw at Burnley last time out.
Darren Ferguson's side are unbeaten in their last four at home, while Leicester have won their last two away games. The reverse fixture took place on the opening day of the season in August, where Leicester ran out 2-0 winners.
Nigel Pearson could name an unchanged lineup after his side's 2-1 win over Wolverhampton Wanderers.
