The Los Angeles Chargers have released Mike Williams, which will save them $20 million against their cap.

Williams appeared in just three games in 2023, catching 19 balls for 249 yards and one touchdown.

The San Francisco 49ers will release Arik Armstead after the two sides were unable to agree to a restructured contract.

Armstead is coming off a season in which he played in 12 games with 27 tackles and five sacks. 

Armstead was slated to count $28.53 million against the 2024 salary cap, which is why the Niners were seeking a reworked deal to reduce that number.

Armstead tore the meniscus in his right knee, an injury he suffered in a Dec. 3 win at the Philadelphia Eagles.

The Seattle Seahawks have released Jamal Adams.

Adams, a three-time Pro Bowl selection, was set to make a nonguaranteed $16.5 million in 2024 and count $26.9 million against the salary cap -- untenable amounts for a player who has been unable to stay on the field or get to the quarterback since his stellar Seattle debut in 2020.

The Seahawks are not using a post-June 1 designation with Adams' release, a source told ESPN. That means they will save $6.1 million against the 2024 cap, according to Over The Cap, while absorbing all of his $20.83 million in dead money right away.

The Kansas City Chiefs are releasing wide receiver Marquez Valdes-Scantling, which will save $12 million against their salary cap.

Valdes-Scantling played two seasons with the Chiefs after signing as a free agent from the Green Bay Packers. He caught 42 passes in 2022 and 21 last season but often had his biggest moments in the playoffs.

Rashee Rice was the Chiefs' leading pass catcher in 2023 with 79.

The Baltimore Ravens have signed Dalvin Cook to their practice squad, according to a source.

Cook, 28, went unclaimed on waivers Thursday after he was released by the New York Jets on Tuesday.

The Ravens are 13-3 and have the AFC's No. 1 seed locked up heading into the final week of the regular season.

Dalvin Cook's disappointing season with the New York Jets came to a premature end on Tuesday, as the four-time Pro Bowl running back was waived with one game remaining, according to his agency.

The move was mutually agreed upon, according to a source, and will allow Cook to catch on with a playoff team. He also restructured his contract to forfeit remaining guarantees, a source told ESPN's Adam Schefter.

The Houston Texans have claimed safety Kareem Jackson off waivers, one day after he was released by the Denver Broncos.

In a corresponding move, Houston placed Jimmie Ward (quad) on injured reserve.

Jackson, 35, has had a tumultuous season that has included two suspensions, most recently for four games. He has been ejected from two games for repeated violations of unnecessary roughness rules.

The New England Patriots waived third-string quarterback Will Grier on Saturday, a source told ESPN NFL Insider Adam Schefter.

That leaves Mac Jones and Bailey Zappe on the depth chart, with coach Bill Belichick yet to announce a starter for Sunday's road game against the New York Giants after he had benched Jones late in the team's most recent game - a Week 10 loss to the Indianapolis Colts in Frankfurt, Germany.

The Indianapolis Colts have released Shaquille Leonard.

With a base salary of $15.6 million, Leonard is due $6.1 million for the rest of the year. Leonard's play this season has dropped after being a Pro Bowler in his first four seasons after entering the league in 2018.

The Dallas Cowboys have released Tristan Vizcaino.

Brandon Aubrey is the only kicker on the 90-man roster after the release of Vizcaino.

Robbie Gould and Mason Crosby remain available, but the Cowboys have yet to express interest in adding a veteran.
