Former world bareback champion rider Kelly Timberman changed his plea to guilty Tuesday on one count of child endangerment and one count of battery.

The two counts came as a result of an incident in January at Timberman's home in Mills while he was supervising his son.

By pleading guilty to the two misdemeanor charges, Timberman gave up his right to a trial by jury and gave his testimony under oath to Judge Thomas Sullins in Seventh District Court.

"I spanked him with a belt and left a mark on him," Timberman said.

Count one of causing, permitting or contributing to the endangerment a child carries a prison term of up to one year, a $1,000 fine or both. Count two of touching a family member in a rude, insolent or angry manner carries a prison term of up to six months, a fine of $750 or both.

Natrona County District Attorney Mike Blonigen said a sentence of a year and a half of supervised probation was recommended.

Timberman's case now goes to a presentence investigation before he receives his sentence.
