The completion of Lucas Oil Sportsman racing from the rain-delayed NHRA Arizona Nationals as well as the Division 7 Lucas Oil Drag Racing Series event at Firebird Int’l Raceway have been postponed. An announcement will be made next week concerning new date or dates and venue or venues for completion of the activities.

According to officials, the manufacturer of the traction compound had supplied a pallet of products that contained a compound that was not suitable for drag racing purposes. NHRA and Firebird officials worked feverishly to correct the issues and despite their best efforts were not able to overcome the conditions.

The  NHRA Arizona Nationals initially was postponed last weekend. Only Top Fuel and Funny Car racing were completed at the event, the second of the 2010 NHRA Full Throttle Drag Racing Series, and those were finished Monday.

Pro Stock competitors only completed one round of eliminations on the scheduled weekend. The remaining three rounds will be conducted during qualifying at the upcoming Tire Kingdom NHRA Gatornationals, March 11-14 in Gainesville. NHRA officials had hoped to complete the Sportsman portion of the national event Friday, Feb. 26, but continuing problems prevented that.. A day later, offiicials scrubbed all of the weekend's activities.
