Longtime Arizona Wildcats broadcaster and rugby coach Dave Sitton died of a blood clot in the lungs, Pima County's chief medical examiner told the Star on Tuesday.
Called a pulmonary embolism, the clot can cause sudden death, Gregory Hess said. Former UA basketball player Shawntinice Polk, 22, died in 2005 of what was later diagnosed as a pulmonary embolism.
Sitton, 58, died Aug. 12 in Tucson. The suddenness of his death led friends to believe he suffered a heart attack. But symptoms of pulmonary embolisms include chest pain and shortness of breath, similar to a heart attacks.
The UA on Sunday held a public memorial service for Sitton, a UA grad who spent the last 40 years in Tucson.
