Portsmouth manager Steve Cotterill will be without two players for the season's opening game at Coventry.
Hayden Mullins and Stephen Jordan are likely to miss out through injury adding to the problems Cotterill faces in fielding an already depleted team.
Mullins has a problem with his knee and Jordan has a calf strain, but Jordan might not be able to play because he may not be registered in time.
Cotterill said:'Hayden has got tendonitis problems with his knee. He went to see a specialist but if he has that injected he will not be able to do anything for six days."
'At this moment in time we need him to keep playing through the discomfort of it because our squad is so short. It's a case of monitoring it and looking at the problem closer to the time.
'As for Stephen, he still has a little calf problem. Maybe we shouldn't have played him when we did in Canada, but we didn't have much of a choice with the squad as it is."
Jordan and Jamie Ashdown were allowed to join the troubled south coast club even though it is still under a transfer embargo, but they have not yet been given clearance by the FA to play league football.
The problems don't stop there for Pompey and Cotterill. Kanu, who is out of contract with Portsmouth and in dispute with the club over his contract extension, may not be eligible to play unless the two parties can come to an agreement and Kanu signs the new contract.
Hermann Hreidarsson and Danny Webber are both definitely out and will be for some time with long term injuries.
Also out of contention for the trip to Coventry are Tom Kilbey with a knee injury and Billy Goddard with a shin injury.
