Persistent rain showers and a forecast for more severe weather throughout the evening Sunday forced NHRA officials to postpone the completion of the inaugural NHRA Four-Wide Nationals to Monday at zMAX Dragway.

Top Fuel and Funny Car competitors completed two rounds of racing before the rain started to fall just past 2 p.m. (ET) at the first NHRA Full Throttle Drag Racing Series event to feature racing in four lanes instead of the traditional two. One round of racing was completed in Pro Stock and Pro Stock Motorcycle.

Racing will resume Monday, weather permitting, at 10 a.m. with the continuation of several classes of racing in the Lucas Oil Series. The Top Fuel and Funny Car final rounds will begin at 11 a.m. and will be followed by the second round of Pro Stock and Pro Stock Motorcycle. Final rounds for Pro Stock and Pro Stock Motorcycle will be completed at approximately 12:30 p.m.

Top qualifier Cory McClenathan, Doug Kalitta, Antron Brown and local favorite Doug Herbert, from nearby Lincolnton, will decide the Top Fuel final. In Funny Car, 14-time world champ John Force, his daughter Ashley Force Hood, Matt Hagan and Ron Capps will race for the Wally at the historic event.

Series leader Mike Edwards, Gainesville winner Jason Line and Phoenix runner-up Bob Yonke are among those still in contention in Pro Stock eliminations. Top qualifier Jeg Coughlin was upset in the first round, along with Greg Anderson, who set a national speed record during qualifying.

Four of the top-five points leaders in Pro Stock Motorcycle were upset in the first round. Defending series champ Hector Arana, top qualifier Matt Smith and past Charlotte winner Steve Johnson are among the two-wheel racers who advanced to the second round.

Tickets for Sunday will be honored on Monday. In addition, discounted $10 tickets will be sold at the gate for the abbreviated show. Children under 12 will be admitted for free with a paying adult.
