Given these circumstances, and in consideration of the disruption of services in nationwide air transportation, the AMA Chevy Trucks U.S. Superbike Championship event scheduled for September 14-16 at Willow Springs International Raceway in Rosamond, California, has been postponed until further notice.

"A number of compelling reasons dictate the postponement of this event," said Scott Hollingsworth, CEO of AMA Pro Racing. "From a purely logistical standpoint, it does not appear feasible to expect cross-country travel to be fully restored soon enough to accommodate attending or participating in this race. Of equal importance are considerations regarding the appropriateness of holding a sporting event in the wake of Tuesday's horrible events.

"Our deepest sympathy and most sincere prayers go out to the thousands of families that have been impacted by these terrible events."

AMA Pro Racing, Willow Springs International Raceway and teams will coordinate the rescheduling of this event, while factoring in other important logistical considerations such as live television.
