BBC Radio Solent understands that the Nigerian is yet to leave his team's hotel in Accra, despite their exit from the tournament on Sunday.

Pompey originally requested that Kanu return to England for treatment after he suffered a knee injury against Ivory Coast more than two weeks ago.

But Kanu is now not expected back in Hampshire until the end of the week.

The striker said at the time of his injury: "Portsmouth wanted me to go back and get treatment in England, but I cannot leave my team-mates."

"Millions of Nigerians are looking up to us to bring them happiness and I cannot leave the team.

"I know it would have been better for me to return to England, but I have to make the sacrifice for my country."

Kanu's Portsmouth and Nigeria team-mate John Utaka is also due back at the Premier League club later this week.
