Huddersfield v Peterborough preview
Peterborough defender Gaby Zakuani will be fit.
The centre-half has been struggling with a shoulder injury but will be available at Old Trafford.
Striker Lee Tomlin (ankle) and midfielder Grant McCann (hamstring) have also sat out training this week but are expected to be fit.
Boss Darren Ferguson has a dilemma at left-back with Charlie Lee returning from suspension to challenge Grant Basey, who impressed in his absence during the 2-0 semi-final second-leg win over MK Dons.
Paul Jones continues in goal after Joe Lewis fractured his kneecap in the first leg.
Craig Mackail-Smith will lead the attack in what could be his final game for Posh with QPR, Norwich and West Ham among the clubs linked with the Scotland striker.
Huddersfield manager Lee Clark will choose from an unchanged squad.
The Terriers are looking to secure promotion by extending their club record unbeaten league run to 28 matches.
Defender Lee Peltier, deployed in central midfield for the second leg of Town’s penalty shoot-out win over Bournemouth in the semi-final, is expected to shake off a slight hamstring strain, while Clark must decide whether to change his formation at Old Trafford on Sunday.
Town have operated in a 4-4-2 formation at home this season, as they did against Bournemouth, but have played with one striker away from home.
Forwards Lee Novak, Danny Cadamarteri and Alan Lee provide Clark with extra options up front, but leading goalscorer Jordan Rhodes is likely to start alongside Arsenal loanee Benik Afobe.
Long-term absentees Alex Smithies (knee), Anthony Pilkington (leg/ankle), Damien Johnson (knee) and Liam Ridehalgh (foot) remain sidelined.
