Officials cancelled the WERA National Challenge Series event at Memphis Motorsports Park this morning after new showers moved in and halted practice.

The first practice session of the day was red-flagged when Scott Brown crashed his GSX-R1000 entering turn one, the crashed bike laying down a stripe of oil.

Riders had to deal with seeping water in turn one and puddles on the rubber-coated drag strip immediately after exiting the final turn of the road course. Mark Junge reported problems with spinning up the rear tire of his GSX-R600 on the dragstrip and Chris Ulrich said his GSX-R1000 was spinning the tire through two gears coming onto the front straightaway.

But the restarted first practice session–for machines 600cc and over–and the subsequent session for machines under 600cc plus SV650 Twins–went off without further incident.

The decision to cancel the race day completely came just before 10:00 a.m. Central Daytlight Time when showers caused the second big-bike practice to be red-flagged.
