The MotoAmerica Superbike/Superstock 1000cc and FIM Moto3 warm-up sessions scheduled for early Sunday morning at Circuit of The Americas (COTA) have been postponed because of poor visibility due to fog at the 3.6-mile road course.

The MotoAmerica Superbike/Superstock 1000cc warm-up session scheduled for 7:30-7:50 a.m. local time has been postponed until immediately before the Superbike/Supersport 1000cc race at 3:30 p.m. local time.

The FIM Moto3 warm-up session was due to start at 8:40 a.m., but the start of that session has been delayed until visibility improves.
