Everything you need to know about Saturday's trip to Cambridgeshire as the Reds take on Posh in Sky Bet Championship action.
The Reds travel south east to the Weston Homes Stadium on Saturday for a 3pm kick-off against Peterborough United.
It's our first trip there in three years, and a big opportunity to try and claw back some points in what has become a very early relegation battle.
During midweek, Barnsley were beaten for the 10th occasion in 11 games. It's a wretched run that stretches back to mid-September.
In what was Poya Asbaghi's first game in charge, the Reds were comfortably defeated by mid-table Swansea City, whose possession-based game made for a tough watch, and whilst it took them until the final quarter of the match to claim the three points, they did so without any fear of a Barnsley comeback.
That 2-0 loss at Oakwell left the Reds in 23rd position, six points from safety as others around us have picked up their own form.
At the weekend we face a Posh side who themselves are struggling for results. They sit in 22nd, directly above the Reds, four points better off.
Led by Darren Ferguson, Peterborough have lost four of their last five fixtures, with their last victory coming on home soil against Queens Park Rangers (2-1).
Former Reds trialist Siriki Dembélé is in decent form for Posh having already scored a handful of goals this season.
Experienced forward Jack Marriott is still missing for the hosts, as are the talented Joel Randall and Ricky-Jade Jones.
As stated earlier, it's three years since our last trip to London Road. That came in the 2018/19 promotion season in League One.
On a dream afternoon for Barnsley, the Reds, having already seen Adam Davies save an early penalty kick, went on to blow away the home side 4-0, with George Moncur, Brad Potts (x2) and Jacob Brown amongst the goals.
There was another classic in this fixture in 2011 as the Reds blew a 3-0 lead, pegged back by Posh only for Craig Davies to clinch a 4-3 victory late on.
Saturday's man in the middle will be John Busby. Into his seventh season as an official, he tool charge of August's 1-0 victory over Coventry City.
He booked eight Reds players that afternoon as a Dominik Frieser goal sealed a first win of the season for Barnsley.
