Grant, still officially Pompey's director of football until paperwork arrives enabling him to be installed as successor to sacked manager Paul Hart, could stick with Jamie Ashdown but highly-rated Bosnian international Begovic was recalled from a loan spell at Ipswich earlier this week.
Veteran defender Hermann Hreidarsson is likely to keep his place after coming back from injury in the 1-0 defeat at Stoke but Grant may recall French loanee Frederic Piquionne in place of Kanu, who made his first Premier League start of the season last week.
Portsmouth (from): Begovic, Ben Haim, Kaboul, Wilson, Hreidarsson, Brown, Yebda, O'Hara, Boateng, Dindane, Piquionne, Kanu, Swift, Hughes, Van den Borre, Mokoena, Belhadj, Mullins, Ashdown.
