ORLANDO, Fla. (AP) — The attorney for three NASCAR fans injured last weekend during a race the day before the Daytona 500 says they are exploring a possible lawsuit, but some experts say they could face tough obstacles in winning damages.

Matt Morgan, the Orlando-based lawyer for the fans, said at a news conference Tuesday than any suit would focus on the safety fence used along the track at Daytona International Speedway. He said he hopes to reach a settlement with NASCAR to avoid a lawsuit.

More than 30 people were injured last Saturday after a horrific wreck in a second-tier NASCAR series race sent chunks of debris, including a heavy tire, into the stands. Morgan declined to provide the identities of his clients, but said two of them were seated directly in front of the crash and sustained injuries ranging from a fractured fibula to abdominal swelling. All have been released from the hospital.
