Is Joey Harringtons career done?

The Falcons retaind Chris Redman today with a 3 year, 9 million dollar contract. D.J. Shockley has one more year on his contract. And the Falcons are very likely drafting a Q.B. with there #3 overall pick in the draft. So dose that mean Joey Harrington is done in atlanta. And if he is done in atlanta. Do you think there is anybody out there that still wants to take a chance on him, at least as a backup?
