"Everybody is calling him, but it's a business at the end of the day," Seattle defensive end Michael Bennett said. "... So all you can do is support him. You want him to be here, but as a player you understand the business side too."
Lynch's absence was expected after former teammate Michael Robinson said Thursday night on NFL Network that Lynch would not show for the opening day of camp.
Seattle coach Pete Carroll said he was disappointed Lynch was not present, while reiterating the team wants him there and intends on him being an integral part of their plans for this season.
But the message was clear that Seattle put a plan in place before Lynch was signed to a four-year contract in 2012 and the Seahawks management is not inclined to stray from those plans.
"We've had a substantial plan working for us for years now and Marshawn was a big part of this plan. Just a couple of years back we made a big statement and made a big effort for him and we wish that he was with us now," Carroll said.
"But this is a tremendous opportunity for the guys getting their shot. Robert Turbin and Christine Michael, they're ready to go and really fired up about this opportunity and are going to try and take full advantage of it."
In Lynch's place, Turbin and Michael took most of the reps at running back Friday. Turbin, from Utah State, is entering his third season, while Michael, from Texas A&M, barely saw the field last year as a rookie as he struggled with the transition between college and the NFL.
Friday's result was building throughout the offseason with Lynch staying away from organized team activities and rumors that he would skip June's mandatory minicamp in protest of his contract structure.
Lynch showed up for the minicamp in June to avoid a hefty fine. But he finally decided to make a stand with the start of training camp.
Manziel admits 'rookie mistakes'
Browns quarterback Johnny Manziel says he "made some rookie mistakes" during the offseason and vowed to be focused on just football in the future.
Speaking on the eve of Cleveland's first training camp practice, Manziel briefly addressed his behavior during the offseason when photos of him partying around the country were a weekly occurrence. Manziel said he has spoken to Browns coach Mike Pettine and general manager Ray Farmer and "we've been on the same page." Manziel said he spoke them about a photo of him holding a rolled up $20 bill, but he provided no other details.
Manziel said he wants to represent the Browns in a "positive manner and a positive light."
The former college star enters his first camp as Cleveland's No. 2 quarterback.
Steelers put off extension for QB
The Pittsburgh Steelers want to reward Ben Roethlisberger for the two Super Bowls he's already won while also making sure the talent around their quarterback is good enough to make a legitimate run at a third ring.
Doing both at the same time isn't an option, at least not this year. Steelers president Art Rooney II said Friday the team is putting off awarding Roethlisberger a lengthy extension until the offseason so it can focus on improving a roster that has missed the playoffs each of the past two years.
Pittsburgh typically renegotiates with its starting quarterback when there are two years remaining on the current deal. Roethlisberger is about to enter the penultimate season of an eight-year, $102 million contract.
Weber linebacker signs with Panthers

Carolina opens its preseason schedule Aug. 8 against Buffalo.
