Peterborough United head to the John Smith's Stadium on Saturday afternoon for a crucial npower Championship encounter (3pm).
Darren Ferguson's men can move out of the bottom three with a victory over the Terriers who were beaten 1-0 at Bolton Wanderers on Tuesday evening.
Posh go into the game on the back of a seven-match unbeaten run, with a goalless draw at Middlesbrough the latest positive result.
Tottenham Hotspur loanee Alex Pritchard has returned to London Road after injury and is included in the squad for the clash with Mark Robins' side. Michael Bostwick has a 'slight chance' of being fit, but Ferguson has confirmed he will definitely be back for the clash with Watford.
Ferguson said: 'It is a big game, bigger than the play-off final because that was then and this is now. Huddersfield manager Mark Robins will get a good work ethic from his lads and it will be a difficult game, as they are all at this level.
'We are all looking forward to it, we are relishing the challenge that lies ahead of us. We know what a win there could do for us and it will be a good test,' Ferguson said.
Huddersfield are expected to be without full-back Jack Hunt who limped out of the defeat at the Reebok Stadium with a hamstring injury.
Posh have sold over 500 tickets for the game in advance with fans able to pay on the turnstiles at the stadium.
