DAVIE, Fla. -- Ryan Tannehill sat in the team cafeteria Friday, his left leg in a brace and propped on a chair as he watched practice from afar with a sullen stare.
He has again been demoted to the role of spectator, perhaps for the entire season.
Knee surgery is an option for the Miami Dolphins quarterback, although it's possible an operation can be avoided, coach Adam Gase said. But even then Tannehill is expected to be sidelined at least six weeks.
Tannehill, who missed the final four games of last season with two sprained ligaments in his knee, reinjured it in practice Thursday. An MRI was inconclusive, and the Dolphins are consulting with a multitude of specialists.
"I wouldn't say second and third opinions -- we're probably going deeper than that, talking to a lot of people, making sure we get the right information," Gase said. "Everything is on the table right now" (see full story).
Steelers: Coach Tomlin's contract extended through 2020
PITTSBURGH -- Mike Tomlin's strong first decade with the Pittsburgh Steelers has earned the coach the chance to work well into a second decade with the organization.
Tomlin and the team have agreed to an extension that will keep the 45-year-old in Pittsburgh through the 2020 season.
Complete coverage of the Philadelphia Eagles and their NFL rivals from NBC Sports Philadelphia.
Tomlin is 103-57 in 10 years with the Steelers, who have captured one Super Bowl, been to another and earned five AFC North titles during his tenure. He is one of eight coaches to win 100 games in their first 10 seasons.
Steelers President Art Rooney said Tomlin "continues to prove he is one of the top head coaches in the National Football League." Pittsburgh went 11-5 in 2016 before falling to New England in the AFC championship game.
Tomlin called his 10 seasons an "amazing experience," adding his focus is on helping the franchise win a seventh Super Bowl.
Patriots: Brady wants to keep past medical issues private
FOXBOROUGH, Mass. -- Tom Brady says he prefers to keep any medical issues in his past private, including whether he had a concussion last season.
In his first comments since the Patriots opened training camp, the quarterback said Friday he "isn't blind" to issues such as CTE, but remains confident in how he tries to avoid injury.
Brady's wife, supermodel Gisele Bundchen, told "CBS This Morning" in May that Brady played through a concussion on his way to a fifth Super Bowl title.
The NFL said it reviewed all reports from independent neurotrauma consultants and trainers who worked at Brady's games during the 2016 season and found no records that indicated he had a head injury or showed concussion symptoms (see full story).
Bills: LT Glenn to see specialist for foot injury
ORCHARD PARK, N.Y. -- Buffalo Bills starting left tackle Cordy Glenn missed his second straight practice because of a left foot injury. Coach Sean McDermott says it's too early to determine whether the player will require surgery.
McDermott provided the update before practice Friday, a day after Glenn traveled to have his injury evaluated by foot specialist Robert Anderson in Charlotte, North Carolina. McDermott declined to go into detail on the nature of the injury by simply referring to it as "general foot soreness."
Glenn was held out of spring practices before being cleared for the start of training camp last week. He was practicing on a limited basis before missing his first session on Thursday.
McDermott didn't provide a timetable in saying he expects Glenn to return to practice sooner than later.
Glenn has been a starter since his rookie season in 2012, and last year became one of the league's top-paid tackles after signing a five-year, $65 million contract extension.
Raiders: It's Marshawn Mania during training camp
NAPA, Calif. -- Marshawn Lynch plowed through the line, dreadlocks swaying on a rare cool summer morning in Napa then juggled the football to the delight of hundreds cheering from nearby bleachers.
They raised phone cameras to capture the self-proclaimed MoneyLynch's every move. A film crew followed, too.
It's Marshawn Mania in wine country. And Lynch sure seems to be loving the attention of his un-retirement, back in that familiar No. 24 jersey, just different colors now that he's with his hometown team.
Lynch joined the Oakland Raiders on a restructured two-year deal following an April trade from Seattle, where he had retired following the 2015 season. Now he has a chance to keep Derek Carr and Co. contending for an AFC West title and a shot at the Super Bowl.
"He's going to run through some people's faces, I think that's what he's going to do," Carr said. "He's going to protect the quarterback. ... He's good at that. Very physical. That part of the game is fun to him. I tend to like to slide or go over people, and he likes to go through them, so I don't have to do it."
Cowboys: Christie to see Jones inducted into HOF
TRENTON, N.J. -- New Jersey Gov. Chris Christie is heading to Ohio to celebrate Dallas Cowboys owner Jerry Jones' entry into the NFL Hall of Fame.
Christie is scheduled to be in Canton on Friday and Saturday to see Jones' induction.
Christie is a lifelong Cowboys fan despite most New Jersey football fans favoring two of the Cowboys' biggest rivals: the New York Giants and Philadelphia Eagles.
He has sat with Jones in his box at many Cowboys games. Once, the two had an awkward embrace caught on camera when the Cowboys won a rare playoff game in 2015.
The Republican governor left New Jersey on Friday afternoon as President Donald Trump arrived in the state for the start of a 17-day vacation.
