Owners of NFL teams plan to discuss the possibility of changing Commissioner Roger Goodell's role in the player disciplinary process, several people familiar with the situation said Friday.

Although it's uncertain whether Goodell's authority would be reduced, the decision to re-evaluate his role resolving appeals is the first solid sign the outcome of Tom Brady's court case could have a lasting and significant impact on his position.

"There will certainly be discussion about that," one owner said, speaking on the condition of anonymity because of the sensitivity of the topic. The owner said he is "not sure where it will lead."

Another person familiar with the league's inner workings said Friday it is too soon to know whether enough owners favor such a change for the NFL to engage the players' union in discussions about possible modifications to the disciplinary process. The union has been pushing for a neutral arbitrator to hear appeals in matters of player discipline, replacing Goodell, who currently occupies that role.

"It will be interesting to see," the person said.

Tebow makes Eagles

Tim Tebow made Matt Barkley expendable. The Philadelphia Eagles traded Barkley to the Cardinals, clearing a roster spot for Tebow after he won a preseason competition for the No. 3 quarterback job.

Arizona sent a conditional seventh-round draft pick to Philadelphia for Barkley.

Tebow will play behind Sam Bradford and Mark Sanchez unless coach Chip Kelly makes a surprise move this weekend.

Etc.

Darnell Dockett, who was signed in March to add some veteran punch to the 49ers' pass rush, was released. The longtime Cardinals defensive end missed the 2014 season because of an ACL injury.

•The Giants released punter Steve Weatherford and acquired Brad Wing in a trade with the Steelers to replace him.

•Bills starting cornerback Leodis McKelvin will miss the start of the season because of an ankle injury. And the Bills released Ikemefuna Enemkpali three weeks after acquiring the linebacker, who broke the jaw of Jets quarterback Geno Smith.

•The Falcons released quarterbacks Rex Grossman and T.J. Yates, leaving Sean Renfree as the backup to starter Matt Ryan. … The Falcons also acquired veteran guard Andy Levitre from the Titans in exchange for a 2016 sixth-round pick and a future conditional pick.
