AP Photo/Steven Senne (AP) - Baltimore's Justin Tucker sent the opening kickoff out of the end zone for a touchback as the Ravens and New England Patriots began their AFC championship game. A win on Sunday would send the Ravens (12-6) to the Super Bowl for the second time and extend the 17-year career of linebacker Ray Lewis, who has said he will retire after the season. A victory would put the Patriots (13-4) in their eighth Super Bowl, tying the Dallas Cowboys and Pittsburgh Steelers for the most all time, and quarterback Tom Brady in his sixth. It would be the Patriots' second straight appearance in the NFL title game and third in six years. The Patriots played without tight end Rob Gronkowski, who broke his left arm a week earlier in their 41-28 divisional win over the Houston Texans. The winner of the game plays the San Francisco 49ers in the Super Bowl on Feb. 3.
