Portsmouth boss Harry Redknapp has decided against offering terms to trialist Mohamed Kallon.
"He's a good player, but we've got Benji, Kanu and Nugent at the moment and they're all doing well and scoring goals for us," said Redknapp.
"For someone to come in he's got to be better than them, he's got to improve us or give us something different.
"So we wont be following that one up and he's gone. I'm pleased with the strikers we've got already."
