The visitors are fourth in the league, six points behind second-place Derby County, but boast a game in hand on those around them, while the hosts have little left to play for as they sit in 14th, equally 16 points above relegation and behind the playoff spots.
Match preview
Bristol Rovers have found themselves battling in the middle of the table for the entirety of this season, never dropping below 17th and failing to venture above ninth place.
After a 17th-place finish last season, new major shareholder Hussain Al-Saeed invested heavily in the summer window signing 13 players, signalling their intent to push higher up the league.
However, a start of four wins, four draws and five losses from the opening 13 fixtures under previous manager Joey Barton was deemed not good enough for the amount invested compared to the rest of the league, resulting in Barton's sacking.
Despite that, interim boss Andrew Mangan and current manager Matt Taylor have been unable to improve on that start as Bristol Rovers have continued to ply their trade in the middle of the table.
With just two games remaining the hosts are guaranteed to be competing in League One once again next year, but Taylor's side will still be looking for victory as a base to build upon for next season.
As for Peterborough, their performances have earned them a guaranteed spot in the playoff tournament come the end of the season, but they will be hoping to go one step further and finish in second place, earning automatic promotion.
They currently sit fourth in the table and six points behind second-placed Derby, but Darren Ferguson's side boasts a game in hand that could see that gap be halved.
That still leaves the outcome of who finishes in second place firmly in Derby's hands, but Ferguson will be hopeful that one of Cambridge United or Carlisle United could produce an upset and give his side the chance to claim that automatic promotion place.
If they are to pull of a miraculous takeover of second place then they must ensure they win all three of their remaining matches, as a Derby win and dropped points for Peterborough would guarantee Ferguson's side to be competing in the playoffs.

Substitute Jonson Clarke-Harris had an immense effect in that victory, coming off the bench in the 79th minute with the score level before assisting one and scoring twice to win the game for his side, potentially earning his place in the starting lineup for this one.
