( CNN ) -- The death of Tom Sparks , a 33-year-old former TV host from California who was participating as a third-season contestant on ABC 's reality show `` Wipeout , '' likely was caused by a pre-existing condition , but the Los Angeles County coroner 's office is still examining all possibilities . Sparks died on November 5 of an apparent stroke that his doctors believe was triggered by a pre-existing disease that causes unnatural blood clotting , according to a statement his father released to the Idaho Mountain Express . Sparks previously had worked in radio in Idaho , according to his résumé . An autopsy was conducted on November 8 , but test results are still pending . `` There 's nothing we can confirm until we look at everything , '' the coroner 's office told CNN . `` We do n't want to jump to any conclusions yet . '' A source close to the production company that produces `` Wipeout '' for ABC said that Sparks began to complain of knee pain while running through the first part of an obstacle course challenge during taping on October 19 . Although Sparks was in good spirits , the spokesperson said , producers pulled him from the course . Medics realized he was also experiencing shortness of breath and sent Sparks to a hospital close to `` Wipeout 's '' set . Between the day of taping and November 5 , Sparks was transferred to Cedars Sinai hospital in Los Angeles , California . The Endemol spokesperson said the company requires all participants to undergo a full physical screening , but it 's highly unlikely that Sparks ' disease -- antiphospholipid antibody syndrome , or APS -- could have been detected , and Sparks did not list it as a pre-existing condition . `` We offer our heartfelt condolences to the family , '' ABC and Endemol said in a joint statement . `` This is a tragic loss and our thoughts are with them at this time . '' Sparks was survived by his wife , Kate , according to the Idaho Mountain Express . The couple would have celebrated their two-month wedding anniversary on November 6 .
