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.
