The Riders have released him. He doesn't seem to be able to hold onto a backup role. I had hope for him when he played in the Grey Cup a few years ago. All things considered, he did pretty good and nearly beat the Riders. Since then, he really hasn't done a whole lot, granted he hasn't gotten a huge amount of playing time.
I can't help but think that after this, he's done. He isn't young either and who would want to pick up a 31 year old for a backup QB?
