She said the autopsy revealed no trauma to Urso's body, along with no blood clots. In addition to toxicology tests, the coroner's office also will take a closer look at what Gorniak referred to as "heart changes."
"What that means is we saw some changes with his heart but we don't know what it is until we examine it underneath the microscope," she said. "So it could be something or it could be nothing. But it's not definitive as a cause of death right now."
Urso played in six games with the Crew and was rehabbing from a sports-groin injury sustained in May. He did not travel to the game at D.C. United on Saturday night.
In a 9-1-1 call provided by police to the Columbus Dispatch, an unidentified female says, "Officers are with him. It's a very drunk person who fell down and now he's unconscious."
It is unclear if the speaker is affiliated with police, fire or an emergency crew or if she is a bystander.
Urso, an Illinois native, played for and was the captain at North Carolina last fall when it won the NCAA championship.
