Posh head to the County Ground for the second leg of the Area final of the Johnstone's Paint Trophy.
Peterborough United are one win away from a trip to Wembley Stadium as Darren Ferguson's men travel to the County Ground to face Swindon Town in the second leg of the Southern Section Area final of the Johnstone's Paint Trophy (7.45pm).
The tie, which is televised live by Sky Sports, is evenly poised at 2-2. Away goals do not count in the competition so if the scores are level at full-time, the tie will go straight to penalty kicks.
An own goal and a first strike for Posh by Kyle Vassell gave Ferguson's men a two goal cushion in the first leg, but the Robins bounced back to level at 2-2 despite having a man sent off.
Posh will be without Conor Washington, Jack Baldwin, Ben Nugent and Nicky Ajose who are all cup-tied. Josh McQuoid is eligible though while experienced midfield man Grant McCann could return after a spell on the sidelines with a thigh strain.
Ferguson said: 'We have faced Swindon quite a few times this season and they have all been tight affairs. We played very well at their place in the league and were unfortunate to lose. We know what to expect and it will be a difficult tie, but one that we are looking forward to.
'It will be a big crowd, I think they are expecting over 10,000, so there will be a good atmosphere inside the stadium. The carrot of Wembley is there and the players know it,' Ferguson said.
The game is not all-ticket for Posh fans and tickets are available at the County Ground.
