Posh travel to Aggborough on Saturday afternoon to face Skrill Premier League side Kidderminster Harriers (3pm).

The third round of the FA Cup is a magical day in the football calender and Peterborough United will be looking to ensure they are not on the wrong end of a shock when they travel to Skrill Premier League side Kidderminster Harriers on Saturday (3pm).

Both sides go into this cup-tie out of form with Kidderminster beaten 6-0 by league leaders Luton Town in their last outing, while Darren Ferguson's men were also beaten by league leaders, Brentford running out 3-1 winners at London Road on New Years Day.

Ferguson will be forced into changes to his starting line-up and substitute's bench with Nicky Ajose, Peter Grant and Kyle Vassell all cup-tied. Lee Tomlin returns from suspension, but the game will come too soon for Tommy Rowe and Danny Kearns. Both are expected to be fit for the league encounter at Swindon Town. Craig Alcock is still sidelined with a calf injury.

Ferguson said: 'Kidderminster have only lost two games at home all season and they play a certain way. They are a bit out of form like ourselves, so both teams will be desperate to get the right result.

'It is a massive game for us. We know what we have to do. The tie is big for financial reasons and obviously to get into round four brings with it the possibility of playing a big side away from home, which would be a great experience for the players.

'We have to make changes to the side because of players being unavailable or cup-tied, but I know I have got enough ability in the dressing room. It is about how we perform on the day. We know they will come at us and we will have to deal with the atmosphere,' Ferguson said.

All Posh fans will need to gain admission at Kidderminster as no tickets have been available in advance.
