After picking up four points from their last two matches, Cheltenham will be looking to avoid defeat for a third consecutive game.
Match preview
After losing 1-0 to league leaders Sheffield Wednesday last Saturday, Peterborough returned to winning ways when they played host to Shrewsbury Town in midweek.
Tuesday's contest appeared to be heading towards a draw after Jonson Clarke-Harris saw his opening goal cancelled out by Tom Flanagan.
However, Frankie Kent proved to be Peterborough's hero, snatching all three points with an 87th-minute winner to seal a narrow 2-1 victory.
The midweek result leaves the Posh in eighth position with seven points separating them from sixth-placed Derby County, who have played a game more.
Peterborough, who are unbeaten in three home games, will be determined to score the opening goal on Saturday, as they have gone on to win 10 of the 11 home league matches where they have opened the scoring.
Cheltenham, meanwhile, lost their final three matches in February by a combined 10-0 scoreline, but they have shown signs of improvement in their last two outings.
After claiming a narrow 1-0 victory over Fleetwood Town last weekend, the Robins played out a goalless draw with Lincoln City in midweek to record a second straight clean sheet.
Wade Elliott's side will head into the weekend in 17th position, and they will be aiming to extend their four-point gap to the relegation zone.
With their last two games taking place on home turf, Cheltenham will now be targeting a positive result on the road after losing six of their last seven away league games.
Having scored just one goal in the opening 30 minutes of their 18 away matches in League One this season, the visitors will be looking to make a quick start on Saturday.
