Daytona International Speedway will install energy-absorbing SAFER barriers to the concrete wall that Kyle Busch hit last month before NASCAR returns in July.

Busch broke his right leg and left foot Feb. 20 when he crashed into a retaining wall that lacked a SAFER barrier.

Daytona president Joie Chitwood said Wednesday the track completed an extensive safety review after Busch's accident and will make numerous changes before the race in July.

The track also will install SAFER barrier on the outside backstretch wall.
