As other runners wrap up their preparation for track and field's world championships, Nick Symmonds plans to seek solitude after being left off the U.S. squad over a uniform squabble.

The defending world runner-up at 800 meters refused to sign a contract that USA Track and Field requires of athletes before they're placed on the team. When the official roster was named Monday, Symmonds wasn't on it despite his win at the U.S. championships in June.

For Symmonds, the issue is Nike's standing as USATF's uniform sponsor. Anyone going to Beijing later this month on the U.S. team is required to wear Nike gear at team functions. Symmonds is sponsored by a rival shoe company, Brooks, and wanted it clearly spelled out what constitutes a team function.

"I guess a small part of me thought they weren't stupid enough to leave me off the team," Symmonds said. "Apparently, they are."

Symmonds, 31, said Nike has been granted too much power.

"I just feel that I can't go out there and put on that Team USA jersey and feel good about it, while all the athletes are being mercilessly bullied and threatened by USATF at the same time," he said. "I just can't ignore it anymore."

The New York Rangers announced they signed the former Los Angeles Kings forward, who was arrested in April and charged with felony possession of cocaine. Reports have said Stoll accepted a one-year, $800,000 contract.

Rangers General Manager Jeff Gorton said the organization spoke to former teammates, trainers and others who have known Stoll in a professional setting. The club was impressed.

Feds explain Armstrong push

The federal government says it wants Lance Armstrong's medical records from his 1996 cancer treatments because they could prove just how far he was willing to go to conceal performance-enhancing drug use from the public and his sponsors.

The government wants to recover more than $30 million in sponsorship the U.S. Postal Service paid Armstrong and his teams. The feds are pursuing whether he told doctors in 1996 he was using performance-enhancing drugs and later sought to bury evidence through lawsuits and charitable donations.

Armstrong's efforts to "blunt this allegation ... were critical to hiding the truth of his doping from, among others, the United States Postal Service," the government said in documents filed last week in a Washington, D.C., court.
