He was 23 years old. "The cause of death at this time is unknown," she told the Associated Press. She said she doesn't know what Haywood was being treated for.
The former leading rusher in the Big XII and Iowa State Cyclone was taken to the hospital early Saturday after waking up feeling horribly ill and vomiting, Iowa State director of media relations Tom Kroeschell told the AP on Sunday.
"This is a time to offer support and deepest sympathy to the family," Cowboys owner Jerry Jones said.
"Our hearts go out to them. This is a tragedy involving a person who was very well-liked and respected by anyone who had the opportunity to know him."
Haywood, considered by most as a second or third team team running back, led the team in rushing in the preseason with 120 yards on 31 carries.
