If Buffalo Bills fans want the backup quarterback to replace Ryan Fitzpatrick, then they better know who to beg for at Sunday's home opener against the Kansas City Chiefs.
Start coming up with signs that involve witty Thigpen puns.
Bills coach Chan Gailey said today Tyler Thigpen remains the backup, and Tarvaris Jackson is the No. 3 as Jackson continues to learn the Bills' playbook.
Gailey said Jackson is "still not ready to go. He's still got a lot to learn. That was a tough situation he was in. He's still learning the whole system."
The Bills acquired Jackson in a trade with the Seattle Seahawks two weeks ago and cut Vince Young, who had been tentatively awarded the backup job in preseason.
