NASCAR president Mike Helton said Tuesday there are two separate issues: the wreck itself, and the fact that Keselowski's car went airborne.
He says NASCAR is reviewing why the car left the track, and adds that NASCAR will meet with both drivers and their car owners to "clean the slate."
On Sunday, Edwards returned to the track after an earlier wreck with Keselowski. Edwards then caused a crash that sent Keselowski's car airborne.
