For the second year, Chattanooga's McKenzie Arena will host a major Professional Bull Riders event.

The Sean Willingham Invitational returns Friday and Saturday at 7:30 p.m.

Tickets are $15–$75 and available here.

The event is named after PBR veteran and Summerville, Georgia, native Sean Willingham, who has been a professional for 18 years. He is currently ranked 99th in the world.

On Friday, fans will have an opportunity to meet PBR riders and country music star Colt Ford in the concourse before the event. 

PBR stars will also be at Crockett Powersports at 4113 S. Access Road from noon to 2 p.m. Saturday. 

If you're a newcomer to the sport, riders attempt to stay on a bull—which averages between 1,600 and 1,700 pounds—for eight seconds. The sport is known for its high risk and is often referred to as "the most dangerous eight seconds in sports."

This year's event includes two-time PBR World Champion JB Mauney and 2016 PBR World Champion Cooper Davis. Other riders include Reese Cates and Alex Cardoza.

Since 1992, PBR has grown to become an international professional bull riding organization with more than 1,200 cowboys.
