The warm-up sessions for the GoPro Daytona SportBike and National Guard Superbike were postponed Sunday morning at Mazda Raceway Laguna Seca due to fog and a resulting lack of visibility. Update: AMA Pro Racing originally announced that the warm-up sessions were cancelled, but the GoPro Daytona SportBike session was actually postponed until 9:30 a.m. local time. The start time of the National Guard Superbike warm-up session was not immediately available.
