The Pro Motocross Championship has pushed back the start of its season until June 13 because of the coronavirus outbreak.
MX Sports Pro Racing, which operates the series, canceled the season-opening Hangtown Classic on Thursday and revised the rest of the schedule a day later.
The opener of the 11-race season now will be in Jacksonville, Florida, followed by a race in Mt. Morris, Pennsylvania, on June 20. The season will conclude Sept. 5 in Pala, California.
