James experienced lightheadedness
James never lost consciousness, and his pulse and blood pressure remained good, said the person on condition of anonymity.
The 320-pound James took part in the two-hour workout in muggy, 80-degree weather and became woozy at his locker. The practice was the second of the day on the third day of training camp.
Dolphins spokesman Harvey Greene confirmed that James was taken to a hospital but said the team would have no further comment until Thursday.
James started 14 games for Miami last year after signing as an unrestricted free agent. He spent his first four seasons in the NFL with the Carolina Panthers.
The 36th overall pick in last April's draft, Ruud finished as the all-time leading tackler in Nebraska history with 432. Ruud will likely compete with Shelton Quarles at middle linebacker and add depth for an aging Tampa Bay linebacker corps.
Frye's signing leaves wide receiver Braylon Edwards, the No. 3 overall pick, as the Browns' only unsigned rookie. The club opens its first training camp under new coach Romeo Crennel on Friday.
Frye's agent, Eric Metz, said he only had to finalize language on the deal and that Frye was expected to sign his first pro contract late Wednesday night.
"I'm real excited," said Frye, who played at Akron. "I can't wait to get in there. I've been a Cleveland Browns fan my whole life and this is a perfect situation for me."
White has already missed three practices, and the longer he is absent, the lower on the depth chart he might fall. The Falcons had initially expected the wide receiver to compete for a starting job, but that likelihood has diminished with each absence.
"Every day that Roddy misses now, the chance of [him starting] becomes less and less," coach Jim Mora told the paper. "If he was here I'd be able to evaluate him but he's not. Hopefully he gets here soon but if he's missing practices, he's not going to start for sure."
White sits behind wideout Dez White on the depth chart, but the pecking order is not set yet, as the Falcons have opted for full competition for each position.
Philadelphia Eagles: With veterans scheduled to report to training camp on Monday, the agent for Corey Simon reiterated what he'd said more than three months ago -- that Simon would not sign the Eagles' franchise tender or attend camps.
Roosevelt Barnes, Simon's agent, simply told the Philadelphia Daily News "no" when asked whether there had been any progress or change in Simon's plans for camp.
Simon told the paper he had "no comment" on the situation.
If Simon refuses to sign the Eagles' 1-year, $5.13 million franchise tender and sits out the season, Simon would forfeit the $5.13 million and remain Eagles' property.
In other news, the Eagles agreed to terms with second-round draft pick Reggie Brown of Georgia, who's expected to challenge for the No. 4 wide receiver role.
The 6-foot-1, 197-pound Brown earned all-SEC honors his senior year, leading the Bulldogs with 53 catches for 860 yards and six TDs. The 24-year-old Brown was a two-year starter at Georgia and finished his career with 144 catches, 12 TDs and 2,008 yards receiving.
Ellison started 31 starts games during his career at Missouri and tallied 171 tackles and 6.5 sacks. He was a first-team All-Big 12 selection as a senior, when he had 60 tackles, 2.5 sacks and four quarterback pressures.
Fincher was a three-year starter at Connecticut and a defensive leader on the 2004 team that went 8-4 and defeated Toledo 39-10 in the Motor City Bowl.
Fincher averaged nearly 12 tackles per game last season for the Huskies and was named All-Big East Conference. He finished the season with a career-high 140 tackles (56 solo), seven pass deflections, two interceptions, five forced fumbles, a pair of sacks and a fumble recovery.
The Saints, who open training camp Friday, did not disclose financial terms with Fincher, the third draft pick to agree to a contract with the Saints.
The 6-foot-3, 215-pounder, who played at UCLA, was the team's sixth-round draft pick. He had 84 career receptions and 1,547 yards, and averaged 22 yards on 67 kickoff returns.
Hayden, a cornerback from Illinois, was expected to report to report Wednesday afternoon to the team's camp, said his agent, Fletcher Smith.
"He's happy with the deal, and he's ready to go,'' Smith said.
The Colts' other signings in the last hours before the training camp opening included center Rob Hunt and linebacker Tyjaun Hagler, both fifth-round picks, and seventh-round pick Anthony Davis, a running back from Wisconsin.
The Colts on Tuesday reached a contract agreement with first-round draft pick Marlin Jackson, a cornerback from Michigan. Jackson's five-year contract is worth nearly $7 million, his agent said.
Miller was one of the Jets' two second-round picks; kicker Mike Nugent, the other second-rounder, remained unsigned.
The Jets, who traded their first-round pick, open camp Thursday.
Miller, 5-foot-10, 202 pounds, was considered a potential first-round pick but his stock fell when he was arrested for disorderly conduct a week before the draft. He was the 57th overall pick.
Miller had 13 interceptions in three seasons at Clemson. The Jets also plan to use him as a kick returner.
White will receive a $420,000 signing bonus. The UCLA running back is expected to be used as a versatile H-back in Redskins coach Joe Gibbs' offense.
The Redskins have yet to sign first-round draft picks Carlos Rogers and Jason Campbell. Players report for training camp Sunday.
In other news, the NFL fined the Redskins $45,000 Wednesday for violating practice squad rules in 2004.
During a Nov. 12 practice, the Redskins used one more practice squad player than they were allowed, leading to the fine.
Kansas City Chiefs: Punter Dustin Colquitt, the Chiefs' third-round draft pick, has signed with the team along with two other draft picks: cornerback Alphonso Hodge, a fifth rounder and quarterback James Kilian, a seventh-rounder.
The three agreed to terms on Tuesday.
