New England linebacker Andy Katzenmoyer walked out of training camp because he was worried about a neck injury.
Coach Bill Belichick said Katzenmoyer contacted him Friday night to apologize for leaving camp following the team breakfast earlier in the day.
"I can't really speak for him, but I would characterize it as he's trying to resolve those issues himself," Belichick said Saturday.
Katzenmoyer's mother, Dianne, said her son is fine.
"There are a couple of concerns about his neck, about the surgery he had last fall," she told The Columbus Dispatch.
Belichick declined to speculate about the length of Katzenmoyer's absence, and said he has not decided whether to fine him.
But he added that Katzenmoyer's decision to leave camp "is not the way we want to do it. But I don't really know enough about the situation right now to make a lot of final decisions or make a lot of intelligent guesses on where things are, let alone where they're going to go."
Offensive tackle Tony Jones, who began his career in Cleveland in 1988, retired Saturday.
Jones, who played for Cleveland from 1988 to 1995, then went on to play on two Super Bowl winners in four years with Denver, told coach Butch Davis and his teammates Friday night that he was done playing.
"From two days of being here, my mind and heart were somewhere else. This team, this organization, these fans deserve better," Jones said at a news conference at the Browns practice facility.
He had signed with Cleveland on July 20, saying he wanted to finish his pro career where it started.
The Deion Sanders saga in Washington is over, and Sanders has to return just $500,000 of his $8 million signing bonus to the team.
And while he will count $5.7 million against the salary cap next year, his retirement will save Washington $3.5 million this season. That money will be used to sign the two top draft picks, wide receiver Rod Gardner and cornerback Fred Smoot.
Coach Marty Schottenheimer said Saturday that negotiations with the two rookies are "ongoing," and he has also said he wants to sign a veteran safety and perhaps a pass-rusher to add some much-needed depth.
The Rams signed fullback Larry Bowie, who was cut by New England on Tuesday, and coach Mike Martz expects him to challenge James Hodgins for the starting job. Bowie played for the Redskins when Martz was in Washington.
"He'll come in and either make James a much better player, or he'll take it away from James, one of the two," Martz said. "He's a devastating blocker and he's the whole package."
Santana Moss, New York's top draft pick, signed a five-year deal that with bonuses and incentives reportedly could reach $8 million.
Moss, expected to compete for a starting job at wide receiver and as a return specialist, was the 16th pick and fourth wide receiver taken in the first round. He was the last of the team's draft picks to sign, and the deal came on the day the players started assembling for the beginning of training camp Monday.
The Titans started training camp with their Pro Bowl running back sidelined. Eddie George's right foot continues to heal from offseason surgery to repair a loose tendon. He expects to begin taking part in drills beginning Aug. 6.
New York Giants guard Glenn Parker, who recently had two moles removed, probably won't practice with the NFC champions until Aug. 6.
Parker is unable to practice because of concerns that his stitches will break. Doctors found skin cancer on Parker's leg last month and removed it. A biopsy showed it had not spread.
Miami signed former Baltimore Ravens tackle Spencer Folau, adding depth to an injury-depleted offensive line.
