RENTON, Wash. -- The Seattle Seahawks have a battle going on right now for the backup quarterback spot between Tarvaris Jackson and Terrelle Pryor.

But in the regular season, when it’s possible that only two quarterbacks will be on the active roster for a game, who is the emergency QB?

“I am the emergency quarterback here,” strong safety Kam Chancellor said Tuesday. “But right now, I’m the fifth-string quarterback. I’m working my way up the depth chart day by day.”

Chancellor is joking, of course, about working his way up the depth chart. But he isn’t joking about being the emergency quarterback.

“If it came down to it, yeah, I’m the guy," he said. “I have about five or six plays down right now. I’m still working on my playbook.”

Chancellor played quarterback at Maury High School in Norfolk, Virginia, passing for more than 2,000 yards and rushing for 500 yards his senior season. In one of the team’s 2005 playoff games, Chancellor passed for 224 yards and two touchdowns and also rushed for 89 yards.

Chancellor, 6-foot-3, also played basketball in high school.

If the team needed it, the Seahawks have another guy who could step in as an emergency quarterback in wide receiver Phil Bates, who was a standout high school quarterback in Omaha, Nebraska. Bates also played some quarterback in college at Iowa State and Ohio but is still fighting for a roster spot at receiver.
