Tucker Hibbert, the reigning FIM Snowcross World Champion, will not attend this year's World Championship because scheduling conflict with an ISOC race.

In 2013, the World Championship will expand from a one-day championship to a three-event championship held in Finland and Russia. The second of three rounds conflicts with an ISOC National Snocross event. In September, Hibbert committed to compete in the full ISOC series where he currently sits second in the Pro Open Points Championship.

“It’s hard to explain how disappointed I am. The World Championship is a really special event for my team and myself. Being an FIM World Champion is an incredible honor and it’s discouraging that I won’t have the opportunity to defend my title this year...
Right now, all my focus is on Winter X Games and the ISOC points championship,” Hibbert said.

Hibbert first competed in the World Championship in 2010. That year, in northern Sweden, he became the first American to be crowned champion in the history of the event. It was his first competition outside of North America. For 2011, the championship moved to Finland. He was the heavy favorite to win but after suffering a mechanical issue in the second of three races, he finished third overall. Last year, the event was held in Russia for the first time. He went 2-1-1 in a three-race format to win his second world title.
