The John Cena hosted “Wipeout” on TBS had a contestant died after completing the game show’s obstacle course, authorities and sources close to the production said. The man, who was in his 30s, was declared dead at a hospital shortly before 7 p.m. last Wednesday, Los Angeles County coroner’s spokeswoman Sarah Ardalani said. The cause of death has not been released, and the man’s name is being withheld until relatives can be notified.

The reality competition show, in which contestants navigate an extreme obstacle course featuring giant balls and pitfalls that often result in spectacular crashes, ran on ABC from 2008 until 2014 and is being rebooted by TBS and production company Endemol Shine North America.

Two people close to the production said the man had completed the course on the show’s set in Santa Clarita, California, when he needed medical attention. He was helped by on-site medical staff until paramedics arrived and took him to the hospital. The people spoke on condition of anonymity because they were not authorized to speak publicly.

TBS issued the following statement on the incident: “We are devastated to have learned of his passing and our deepest sympathy goes out to the family.”
