A motorcyclist was critically injured after he crashed into a loose horse on Main Street Friday night.

Travis Fornelius, 18, Farmington, was southbound on Main about 9 p.m. when he ran into four horses that had escaped a nearby corral, said Centerville Police Sgt. Paul Child.The victim apparently did not notice the horses until just before hitting one of them at 1350 North, Child said. Fornelius, who was not wearing a helmet, was knocked off the bike and sustained primarily head injuries.

It is unknown how fast the motorcycle was going, but the speed limit on that part of the road is 40 miles per hour, Child said. For-ne-lius was taken by medical helicopter to LDS Hospital where he was listed in critical but stable condition Saturday night.

The horses apparently had escaped from a private corral at 1000 North and 100 East, Child said. However, "it is unknown exactly how they got out."

The corral fence was inspected after the accident and it appears to be in good condition, he said.

The injured horse was treated by a veterinarian and is expected to live.
