Some Daytona fans out of hospital
CHARLOTTE, N.C. ( David Newton / ESPN.com ) -- Five of the seven injured fans taken to Halifax Health in Daytona Beach, Fla., following Saturday's horrific Nationwide Series crash have been released from the hospital.
The two that remain are in stable condition, a hospital spokesperson told ESPN.com on Thursday.
At least 28 fans were injured by debris when Kyle Larson's car went airborne into the catch fence on the last lap of the Nationwide opener at Daytona International Speedway. Fourteen were treated and released at the track.
The most serious of the injured were transported to Halifax Health. Two were listed in critical condition, one life-threatening with head trauma, upon arrival. They remain hospitalized.
Three of those injured have retained an Orlando, Fla.-based law firm -- Morgan & Morgan -- to represent them in potential personal injury suits. Attorney Matt Morgan told ESPN.com much of his firm's investigation surrounds the catch fence that was compromised when Larson's car struck it at a crossover gate.
NASCAR is conducting its own investigation. Tom Gideon, the director for safety at NASCAR's Research and Development Center in Concord, N.C., will head it up.
Robin Pemberton, NASCAR's vice president for competition, said on Tuesday that Larson's car has been impounded. He noted, "We haven't begun to look at it."
Pemberton said there is no timetable for when the investigation might be completed. He said it was too early to determine if the crossover gate played a role in how the accident unfolded or if the tire that injured fans went through or over the catch fence.
