OSU fan Daniel Boyington, 30, of Yukon, said he rushed onto the field with his brother after the first goal post came down and fell and broke his collarbone.
He said he was in a clear end zone, running around and celebrating when the person in front of him tripped and fell. Boyington jumped over the person and landed hard on his right side.
“I really didn't feel it until I started walking back to the car,” he said.
“My wife took me to the emergency room this morning, and I broke my collarbone.”
Boyington said he has been an OSU fan since he was 5. When the Cowboys pulled off the 44-10 defeat against the Sooners, he said he couldn't help but join the crowd and be apart of the celebration.
“This way I'll never forget the game,” he said, adding that he was glad he wasn't in a heavy populated area of the field or else he might have been trampled.
OSU Police Capt. Richard Atkins said several people were injured by jumping over the walls of the stadium stands, and many had twisted ankles because they didn't realize how high the stands were.
One woman wrote Sunday on Twitter that she saw a man jump onto the tarp above the locker room and fall to the ground.
Atkins said he's received a report of a man who jumped from 15 feet and landed on his back on the concrete. “It's farther down than it looks,” Atkins said. “We put people in place that tell them not to.”
But when the final seconds ticked down, the field became a sea of orange, and fans started tearing down the goal posts.
Atkins said no injuries were reported due to the tearing down of the goal posts. He said most people might have had smashed fingers or were pushed around, but they didn't suffer any significant injuries.
Shyla Eggers, director of public relations at Stillwater Medical Center, said the hospital staff received six patients from ambulances and two others were brought in by cars. She said the injuries ranged from ankle sprains, ankle fractures to back and heel sprains.
She said two people injured after the game are still at Stillwater Medical Center, waiting to undergo surgery for ankle fractures. The other six have been treated and released.
“We haven't seen anything like this in what I can remember in the last 12 years,” she said.
