How conveniant to pull his hamstring at the "last minute". Questionable to me.
Convenient? I think I know what you're trying to say here, but Andy Johnson isn't an American NBA star. I suspect Johnson would kill Darren Bent for the chance to play for his country. Or at least rough him up a little. Maybe call him a bad name. There are some high-profile "retirees" from international football - Scholes, Makelele - and if this was a friendly and Johnson played for Man United you might, might, have something. But for the most part English players consider it an absolute honour to represent their country.
