If the Broncos' 2015 season goes the way he hopes, Peyton Manning will earn back every penny of the $4-million pay cut he took Thursday.

No. 18 made his return for an 18th season official by passing his physical a day after agreeing to a revised contract that calls for him to make $15 million in the 2015 season. The new deal he signed after getting a clean bill of health includes incentives of $2 million each for winning the AFC title and the Super Bowl.

Manning left the team's headquarters without speaking to the media. He was noncommittal about returning after a playoff loss to the Colts, but he determined he still had the health and hunger to keep playing at 39 for new coach Gary Kubiak.

Manning had a terrific first half of last season but his play slipped dramatically in the second half, when a nagging thigh injury affected his accuracy.

Wilfork, Pats parting ways

Defensive tackle Vince Wilfork said he will not be back with the Patriots next season, ending an 11-year stay in which he won two Super Bowls as the defense's cornerstone. Wilfork tweeted that the team told him it will not be picking up his option for 2015, making him eligible for free agency.

He was due to receive a $4-million roster bonus by Monday and would have gotten $14 million over the next two seasons if it had been picked up. The Patriots did not immediately respond to a request for comment.

Dockett signs with 49ers

Defensive tackle Darnell Dockett has signed a two-year contract with the 49ers after playing all of his 10 NFL seasons with the Cardinals. Agent Drew Rosenhaus confirmed the deal. Dockett, 33, sat out all of 2014 after suffering a knee injury in training camp.
