Video: Oklahoma's 'Sooner Schooner' Wagon Tips Over During Game; Ponies Run Off

It's telling how well things are going for the Oklahoma Sooners this season that the biggest problem they've had on the football field involved their mascot. 

During Saturday's matchup against the West Virginia Mountaineers at OU Memorial Stadium, the Sooner Schooner crashed as it was circling the field while celebrating the team's fourth touchdown:

Oklahoma said in a statement after the accident that none of the riders or ponies were injured, and it believes the crash was caused by uneven weight distribution in the back of the wagon:

"The Sooner Schooner tipped over today. We believe it was the result of weight distribution among riders in the rear of the wagon. Three individuals were evaluated at the stadium and released. All others reported that they were uninjured. 

"Upon initial evaluation, it also appears the ponies are uninjured. Medical staff responded immediately as did the expert horse handlers and veterinarian who staff all games. We are grateful that the injuries were not serious and for the staff members who responded so well."

The Sooner Schooner has been a staple at Owen Field since 1964. The wagon is pulled by ponies Boomer and Sooner V.
