Fan injured by debris at NHRA race

A spectator attending the NHRA Arizona Nationals was seriously injured after a crash involving NHRA Top Fuel driver Antron Brown.

The unidentified female was struck by debris at Firebird International Raceway in Chandler, Ariz., when Brown lost control of his dragster. She was airlifted to Good Samaritan Hospital, according to the Arizona Republic .

Brown, who was racing against driver Troy Buff, lost control when a rear tire came off his car, sending it into a retaining wall. Brown was unhurt but was sent to Chandler Medical Center for further observation, the Republic said.

"It felt like the back end just dropped out and the car started pitching end over end," Brown said, according to SPEEDTV.com. "At that point, I was upside down, and in my mind, things were going crazy. I was just hoping I didn't go into Troy or into the other lane. The next thing I knew, I hit the wall. I saw a little burst of flame come around my head, and I saw sparks. The Safety Safari guy was right there, and the next thing I knew somebody was trying to help pull me out of the race car."

NHRA officials are currently investigating the incident, the Republic said.
