Hangtown’s Lucas Oil Pro Motocross Championship opening round has been cancelled due to the ongoing coronavirus outbreak.

The Californian stop is the first outdoor national to be impacted by the current pandemic, with more cancellations or postponements expected in the coming weeks and months.

In a statement, Pro Motocross says it’s continuously monitoring the ongoing developments surrounding the coronavirus, both domestically and internationally, and has taken a proactive stance in discussing various amendments to the 2020 event schedule.

Alongside event promoters, series partners, and race teams, the promoter is taking a collective approach to determining a practical and effective course of action for each of the remaining nationals, and the entire series as a whole.

The current Monster Energy Supercross series has been put on hold, with no further details yet of it recommencing.
