AMA Pro Racing and Clear Channel Motorsports have announced that Friday practice for this weekend’s opening round of the THQ AMA Supercross Series in Anaheim has been cancelled due to inclement weather.

Steady rains have prevented crews from being able to load-in the dirt at Angel Stadium resulting in a delay in track construction.

While Saturday’s schedule, including practice and qualifying heats, is expected to run as planned, severe weather could impact the event schedule further.  Additional information will be issued if necessary.
