Portsmouth striker Kanu is pressing for a recall at home to Blackburn on Sunday as he looks to secure a place for next month's FA Cup final.
However, manager Harry Redknapp could decide to give on-loan Milan Baros another run alongside cup-tied top scorer Jermain Defoe.
David Nugent, who scored for Pompey reserves on Tuesday, and Pedro Mendes, left out of the squad for the 3-1 defeat at Manchester City, are both nursing "slight knocks" but could be among the substitutes.
Lauren, right-back last after Glen Johnson fell ill, may switch to the left this time in place of suspended Hermann Hreidarsson.
Defender Noe Pamarot has returned to training after 10 weeks out with a knee injury but is not yet back in contention.
Blackburn manager Mark Hughes looks set to name an unchanged side.
Hughes will stick with the team that drew 1-1 with Manchester United last weekend as Rovers bid to keep alive their slim hopes of European qualification.
Blackburn have no fresh injury worries, although Matt Derbyshire is facing an operation on a hernia problem so may not rejoin the squad.
Squads:
Portsmouth: James, Johnson, Campbell, Distin, Lauren, Diarra, Diop, Muntari, Kranjcar, Utaka, Baros, Defoe, Kanu, Davis, Nugent, Hughes, Pedro Mendes, Aubey, Begovic.
Blackburn: Friedel, Emerton, Samba, Nelsen, Warnock, Bentley, Reid, Vogel, Pedersen, Santa Cruz, Roberts, Mokoena, Ooijer, McCarthy, Dunn, Olsson, Khizanishvili, Brown.
