Lemuel Jeanpierre played the final three quarters at right guard against Baltimore. McQuistan had been practicing at left guard before this week, when he now switches sides.

McQuistan started three games at left guard for the Seahawks earlier this season while Robert Gallery was out with an injury to his abdominal muscle.

McQuistan previously played for offensive line coach Tom Cable when the two were in Oakland, and he said that familiarity has helped with his versatility.

Being the backup, when you install, you learn it both ways," McQuistan said. "It's the same calls, just it's on the right or left side."
