Police to Joe Flacco -- Don't Worry, We Got Your Back!!

Joe Flacco got some pretty solid protection in New Orleans last night -- both on and off the field -- 'cause after he won the game, the cops made sure no one laid a hand on the Baltimore Ravens QB.

Flacco got the Super Bowl MVP treatment from police following his big win ... 'cause the boys in blue made sure Joe and his lady friend were as safe as they could be when they got into a waiting car outside of the team hotel to head to the post-game festivities.
