Patriots right tackle Marcus Cannon left Sunday's game against the Broncos in the first quarter with an ankle injury. Cannon's return is questionable. Eight-year veteran Will Svitek replaced Cannon at right tackle. Cannon, who was injured on a strip sack of quarterback Tom Brady when defensive end Von Miller beat left tackle Nate Solder , headed to the locker room with members of the team's athletic training and medical staff. Terrance Knighton recovered the fumble and returned it to the 10.
