"I just received an email from Brian Marwood's secretary, a lady at the club called Claire, telling me to report for training on July 9.
"But when I spoke to the other players I found out the first team was leaving for the pre-season tour of the USA on July 8.
"And I heard this was the same with at least six other players."
Craig Bellamy, Roque Santa Cruz, Shay Given, Wayne Bridge, Nedum Onouha and Michael Johnson are also in the cold.
He added: "What is the point of me coming in to train and they all are in America? I will train on my own."
