Keith Urban will be kicking off the 2013 NFL season opener with a performance during NBC’s pregame show on Sept. 5. Urban will perform on a floating stage on Baltimore’s Inner Harbor before the Baltimore Ravens face off against the Denver Broncos in Colorado. Urban’s Inner Harbor performance will be part of a free concert celebrating the Ravens’ victory in this year’s Super Bowl XLVII. It will serve as the lead-in to the Ravens-Broncos game, which will be hosted at Denver’s Sports Authority Field. Country singer and “The Voice” winner Danielle Bradbery will sing the national anthem.
