A seven-car wreck during practice in Daytona Beach, Fla., for NASCAR's Pepsi 400 sent driver Darrell Waltrip to the hospital with a fractured leg, fractured elbow and concussion.

Terry Labonte and Dave Marcis were less seriously injured in the melee, in which six cars, including three of the eight fastest qualifiers, were so badly damaged their owners will have to use backup cars in today's race.

Waltrip, 43, who had qualified to make his 500th start, instead will be sidelined two months or more, a doctor at Daytona International Speedway said.

Labonte and Marcis, treated and released, said they hoped to be well enough to start the race, although each had a replacement driver standing by.

Labonte's Oldsmobile was leading a pack when it hit a patch of grease and went sideways. "He lost it . . . and stopped up the race track, and we just started piling in," Mark Martin said. "Cars were going everywhere."

The drivers in the replacement cars must drop to the rear of the pack in today's warm-up lap -- including Martin, who qualified for the front row next to pole-sitter Greg Sacks. . . .
