The Franklin County Coroner says an autopsy performed on 22-year-old Columbus Crew midfielder Kirk Urso yesterday is inconclusive. Jan Gorniak says indications point to "an apparent natural death" pending toxicology test results that will not be finalized for four to six weeks. Gorniak says the autopsy showed changes in Urso's heart which may not have contributed to death. Urso died Sunday hours after collapsing at a downtown Columbus bar.
