A track worker remains in a Detroit area hospital after sustaining serious injuries, although in stable condition, following a post-race accident in Saturday’s Chevrolet Sports Car Classic at the Raceway at Belle Isle Park.

According to IMSA, the unidentified male sustained broken ribs, a collapsed lung, as well as injuries to his spleen and kidney after being involved in a multi-car GTD accident following the checkered flag in the 100-minute race.

Track workers were attending to the No. 58 Wright Motorsports Porsche 911 GT America of Jan Heylen in Turn 1 when James Davison’s No. 007 TRG-AMR Aston Martin V12 Vantage slid out of control, in wet conditions, into the rear of a safety truck.

Two additional GTD cars were collected, with all drivers having escaped injuries in the accident.

“IMSA has been informed that the safety worker at a Detroit area hospital who was injured during Saturday’s race is in stable condition with a number of broken ribs, collapsed lung and a non-operative injury to his spleen and kidney,” a statement from IMSA read.

An additional track worker was evaluated and released from the trackside medical center immediately following the race.
