The experienced playmaker made his return from two months out with a bruised marrow in last weekend's 3-1 FA Cup win over Chesterfield, scoring a goal in the process.
But he suffered a nasty gash to his shin during the game and has had stitches this week in a bid to recover in time for the clash with Stuart McCall's men.
Should Igoe fail to recover, Marvin Bartley is the likely candidate to deputise.
Mark Molesley (foot) and Shaun Cooper (hip) are out, though, as manager Eddie Howe looks to get his League Two leaders back to winning ways after their 4-0 thrashing by Rochdale last time out.
Howe this week turned down the opportunity to replace Darren Ferguson as Peterborough's manager.
