Kyle Busch has been involved in a multi-car accident in his return to Daytona International Speedway.
Busch spun nine minutes into the first practice session at Daytona when he was bumped from behind by Brad Keselowski. As Busch's car spun down the track, he was hit squarely in the side by Greg Biffle.
Those two cars then spun into Martin Truex Jr., and the scrum was hit by Denny Hamlin. Also caught up in the crash was Carl Edwards, as Joe Gibbs Racing had three cars involved in the crash.
Busch is back at Daytona for the first time since he broke his right leg and left foot when he crashed into a concrete wall the day before the season-opening Daytona 500.
