* Haywood was pronounced dead at 3:27 p.m. Sunday when his family decided to take him off life support after he had been in a coma for roughly 36 hours at the Medical Center of Arlington.
An autopsy on Haywood revealed "no obvious cause of death," a Tarrant County Medical Examiner's spokeswoman said.
"They did not see anything that could have caused this death based on the autopsy," said Anderson, who also said Haywood's medical records were collected from the south Arlington hospital.
"We are looking at the blood samples taken from Mr. Haywood and what treatment was given to him at the hospital. But we are not releasing any of the information collected at the Arlington hospital until we complete all of our testing."
Tarrant County medical examiners are testing Haywood's blood and organ samples. Blood testing -- called toxicology -- reveals what substances are present in a person's body before death. Haywood's tests are expected to take two to three weeks, Anderson said.
His wife Crystal, who is eight-and-a-half months pregnant with their second child, said the cause of death "is important, but I can't worry about that right now."
According to Crystal, nothing out of the ordinary happened Friday to warn her of a potential tragedy.
She said Haywood went to sleep in apparent good health before beginning to vomit around 4 a.m. Saturday.
"He woke me up," Crystal said. "He was choking. He was vomiting. I got him to roll over and stop vomiting. He then started to snore real loud. He never woke up during any of this. Then the snoring abruptly stopped. He wasn't breathing and I couldn't get a pulse."
Crystal administered CPR to her husband at their Arlington home until paramedics arrived.
She said doctors briefly got a pulse when he got to Arlington Medical Center, but that Haywood was considered brain-dead during most of his stay in the hospital's intensive care unit.
Crystal and Ennis are both natives of Dallas. They met in middle school but didn't start dating until both were at Carter High School. The two were married last August and have a 3-year-old daughter.
"I am trying to hold up," said Crystal. "All I ask is for prayer."
* Pat Summerall may have called his last game for Fox but he may not be done as a broadcaster. Summerall, who retired last week from Fox, said he spoke with Cowboys owner Jerry Jones about being involved in Cowboys broadcasts. Summerall said that if he were able to create his role, he'd like to do a halftime commentary. He'd also like to do a weekly show with either Jones or Cowboys coach Bill Parcells, with whom Summerall has a close and longtime friendship.
"Bill doesn't want to do a show but he has said to me 'If I do it, I'll do it with you,' " Summerall said. "I very much would like to be a part of his first season. If there is failure, I'd like to be there to help. If success, I'd like to be a part of it."
* Despite selecting two cornerbacks in the draft and signing free agent Donald Mitchell, the Cowboys are seeking more help at the position. The team worked out veteran free-agent cornerback DeRon Jenkins at the team's Valley Ranch headquarters last week.
However, the Cowboys have not decided whether to offer Jenkins a contract. More to the point, they worked out Jenkins to see what he had in case they needed help in the future.
The Cowboys' roster of cornerbacks includes rookie draft picks Terence Newman (fifth overall) and B.J. Tucker, Mitchell and holdovers Mario Edwards, Derek Ross, Pete Hunter and Markese Fitzgerald. Ross and Newman are the projected starters in 2003.
Jenkins, 29, is a seven-year pro, but has played for four teams -- Carolina, San Diego, Tennessee and Baltimore -- in the past four years. He has 50 career starts, but only six in the past two years.
