I have been saying for a couple of months that he is not a nailed on starter for us, which for a player of his reputation and skills is probably unacceptable to him. An old coach and new environment might be what he needs.
Willises, Carr, Young, Ashley, etc. Lots of options and combinations without him as it is. Shame if it is true. He wants international rugby and needs to get fit and to play a run of games.
