The hosts are currently sitting in 12th place in League One, while the Royals are two points better off in 10th position.
Match preview
The Posh have embarked on an impressive run of form since they fell to a narrow 1-0 defeat to Bolton Wanderers at the end of October.
Darren Ferguson's side recorded a 4-2 victory in their FA Cup first-round clash with Newport County, before they scored four more goals in a home victory over Crystal Palace Under-21s in the EFL Trophy.
Peterborough produced another free-scoring display in their derby clash against Cambridge United earlier this month, with Kwame Poku netting a hat-trick in a 6-1 victory.
As a result of that win, Peterborough have now gone eight competitive home games without defeat since they lost 2-0 to Wrexham on August 31.
With 31 goals to their name this season, the Posh are currently the league's second-highest scorers behind Wycombe Wanderers, and they will look to showcase that firepower on Saturday as they go in search of a victory that would move them above Reading in the table.
Reading have struggled for consistency in recent times, having won two, drawn one and lost two of their previous five matches in all competitions.
The Royals began that run of results with a heavy 4-1 defeat against Stockport County, before they returned to winning ways with a 2-0 victory over Fleetwood Town in the FA Cup.
Reading have competed in the EFL Trophy in two of their last three matches, losing to Cheltenham Town and beating Newport County either side of a 1-1 league draw against Stevenage.
They will be fully focused on league action this weekend as they look to improve on their travels after seeing their opening seven away league games produce one win, two draws and four defeats.
However, their hopes of claiming all three points on Saturday may be tempered by the fact they have failed to win any of their last five away games against Peterborough (D2, L3).
