Portsmouth will add Bjorn Helge Riise to their squad.
The 28-year-old Norway midfielder has joined Pompey on loan from Fulham and could make an immediate debut against Posh.
Boss Steve Cotterill is still without winger Luke Varney and striker Dave Kitson while defender Aaron Mokoena is a doubt after limping off against Blackpool on Saturday.
Varney serves the second game of his three-match ban following his red card at Hull last week, and Kitson is missing with a rib injury.
Norwegian forward Erik Huseklepp should keep his place in attack after his first goal for the club secured a dramatic 1-0 win over Blackpool on Saturday.
Peterborough will be without Lee Tomlin while Gabriel Zakuani is a doubt for the game.
Tomlin is set for a spell on the sidelines after suffering suspected ligament damage during the defeat to West Ham on Saturday.
Posh will not know how long the forward will be out for until he has undergone a scan on his knee but manager Darren Ferguson is fearing the worst.
Zakuani received pain-killing injections to enable him to nurse a broken bone in his foot through another 90 minutes at Upton Park.
However, two games in quick succession could cause further damage and a late decision will be made on the defender's fitness. On-loan Manchester United youngster Scott Wootton is on stand-by to replace him.
Meanwhile, Ben Gordon has been recalled from his loan spell by Chelsea because of his failure to break into the first team. Gordon has been unable to dislodge summer signing Craig Alcock from the left-back spot.
