A thunderstorm delayed kickoff in Kansas City.

The lightning sent both teams back to their locker rooms and fans were sent out of the stadium seats and back into the concourse.

Players are scheduled to return to the field at 7:00 p.m. CT for a 25-minute warmup, followed by a 14-minute pre-game ceremony.

Kickoff is tentatively scheduled for 7:40 CT.

A rainbow hung over Arrowhead Stadium as fans returned to their seats around 7 p.m. local time.

The Chiefs and Ravens faced off in the AFC Championship Game last season, with Kansas City winning 17-10 in Baltimore to clinch their second consecutive Super Bowl title.
