The International Motorsports Association says it has been informed that a safety worker injured in a race May 30 at Belle Isle has been released from the hospital.
IMSA spokesman David Higdon said Sunday the worker has been discharged and returned home. The IMSA previously said the worker had broken ribs, a collapsed lung and injuries to his spleen and kidney.
Several cars were involved in an accident scene at the end of the TUDOR United SportsCar Championship race, including one car that crashed into a safety truck that was on the track. One safety worker was evaluated and released from the infield care center, and another was hospitalized.
The IMSA says it launched a review in collaboration with the Detroit Grand Prix to determine what happened.
