The New England Patriots have released Mike Nugent and agreed to terms with Nick Folk, according to a source.

Folk last kicked with the Tampa Bay Buccaneers in 2017.

Nugent, 37, was signed on Oct. 3 after the Patriots placed Stephen Gostkowski on season-ending injured reserve with a hip injury. Nugent appeared in four games, and was 5-of-8 on field goals and 15-of-16 on point-after attempts.

The Baltimore Ravens have signed Willie Snead to a one-year, $6 million contract extension.

He would have been an unrestricted free agent at the end of the season.

Snead ranks third on the team with 15 catches for 223 yards and two scores.

The Arizona Cardinals have agreed to sign Alfred Morris.

David Johnson is currently battling an ankle injury, leaving the Cardinals thin at running back.

The Oakland Raiders have signed Darren Waller to a three-year, $9 million extension.

Waller was scheduled to be a restricted free agent in 2020.

Waller, who served a pair of suspensions for failed drug tests while with the Ravens, has gone public with his fight for sobriety, which reached two years during training camp.

Waller has caught a team-leading 37 passes for 359 yards through five games for the 3-2 Raiders.

The New England Patriots are expected to re-sign Benjamin Watson.

Watson was released on Oct. 7 by the Patriots when they didn't have a roster spot following his four-game PED suspension. 

Watson spent training camp with the Patriots and has experience in their system. 

"Ben's a great player. He's been a great player for this team, for other teams. He's had an incredible career," Brady said last week. "He was right next to me [in the locker room], and for as great as a player he was, he was 10 times a better person, just the highest integrity. I can't say enough good things about Ben, what he's meant to me, my family, our team."
