NASCAR has settled a lawsuit by a fan who suffered traumatic head injuries after being struck by flying debris from a 2013 crash at Daytona International Speedway.

According to ESPN, the suit stated that the fan, Allen Davis, was sitting in the upper deck, and “was struck in the head by a heavy piece of debris and suffered a catastrophic, traumatic brain injury.”

The accident occured on the final lap of the NASCAR Xfinity Series race in February 2013, in a multicar crash as the leaders neared the finish line. Kyle Larson’s car went airborne into the catchfence.

The accident sent debris flying into the grandstands, injuring more than 30 fans. Davis sued both NASCAR and Daytona’s parent company, International Speedway Corp., in 2015. Terms of the settlement are confidential.

ESPN reports Davis’ lawsuit was the final pending suit. Disposition of the other suits was not available.

By settling out of court, NASCAR avoids having its investigation of the accident made public. Davis’ attorney had sought access to that investigation report, but NASCAR and the speedway refused, citing protection under attorney-cient privilege.
