The Giants signed Austin to a one-year contract worth up to $4.5 million Thursday, Adam Schefter of ESPN reports.

It's a nice landing spot for Austin, in the sense there isn't a whole lot of proven competition at the wide receiver spot behind Malik Nabers (knee), as Austin looks like a current favorite to be part of the team's three-wide set alongside Malik Nabers (knee) and Darius Slayton after Wan'Dale Robinson left in free agency. Austin failed to gel with Aaron Rodgers in Pittsburgh last season, securing just 31 of 55 targets for 372 yards and three touchdowns across 14 regular-season appearances. Austin averaged 15.2 yards per catch in 2024 and offers theoretical big-play potential.

The Bucs signed Muhammad to a one-year contract worth up to $6 million Thursday, Ian Rapoport of NFL Network reports.

Muhammad turns 31 years old later this month and is coming off a career year with the Lions. He appeared in all 17 regular-season games and finished with 25 tackles (15 solo), including a by-far career-best 11.0 sacks, on just 41 percent of the defensive snaps. Seeing all one-on-one matchups working opposite Aidan Hutchinson certainly worked in Muhammad's favor, and he'll try to build on the big output with Tampa Bay alongside Yaya Diaby.

The Cowboys released Grier on Thursday.

Grier inked a reserve/future contract with the team last month but is now out after Dallas signed Sam Howell as the team's QB3 this week. The 30-year-old Grier hasn't appeared in a regular-season NFL game since his 2019 rookie season with Carolina.

The Dolphins signed Wilson (hamstring) to a one-year contract Thursday, Adam Schefter of ESPN reports.

Wilson was a fourth-round pick by the Cardinals in the 2021 Draft and spent nearly three full seasons with Arizona before being waived in December of 2023. He then spent the past two seasons with the Patriots and Bengals. Wilson appeared in just four regular-season contests last season before being placed on injured reserve with a hamstring injury. He remained there for the remainder of the campaign. Wilson, who will presumably be past his hamstring issue by the time the Dolphins take the field, will compete for a job in the team's secondary.

Huff informed the 49ers on Thursday that he's retiring from the NFL.

Huff is still just 27 years old and remained productive for San Francisco last season, recording 30 tackles (14 solo), including 4.0 sacks, and a pair of forced fumbles across 15 regular-season appearances. He spent the first four seasons of his career with the Jets, followed by one-year stints with the Eagles and Niners. Huff wraps up his career with 24.0 sacks across 81 regular-season contests, including 21 starts.

The Falcons signed Ebukam on Thursday, Adam Schefter of ESPN reports.

Ebukam turns 31 years old in May and missed the entire 2024 season due to a torn Achilles. He appeared in 14 regular-season games with the Colts last season, logging 33 tackles (22 solo), including 2.0 sacks, and one fumble recovery on just 43 percent of the defensive snaps. He'll try to help Atlanta's pass rush next season.

The 49ers signed Greenlaw to a one-year, $7.5 million contract Thursday, Ian Rapoport of NFL Network reports.

Greenlaw spent the first six years of his career with San Francisco before signing with the Broncos last offseason. Greenlaw went on to miss more than half of the season due to quadriceps and hamstring injuries, appearing in just eight regular-season contests. He's made just 10 regular-season appearances across the last two seasons due to lower-body injuries. Greenlaw knows the system and is a veteran option for a linebacker group that dealt with a rash of injuries during the 2025 campaign.

The Seahawks are slated to sign Wilson to a one-year deal worth up to $2.1 million, Ian Rapoport of NFL Network reports.

While working as Josh Jacobs' top backup with Green Bay in 2025, Wilson recorded 496 yards and three TDs on 125 carries, along with 99 yards on 15 catches in 17 regular-season games. With Kenneth Walker departing via free agency and Zach Charbonnet having suffered a torn ACL in January, Wilson could potentially earn a key early-season role in a Seattle backfield that also includes George Holani and Kenny McIntosh, though it's possible that the team adds further RB depth in the coming weeks and months.

The Chiefs signed Kohou on Thursday, NFL reporter Jordan Schultz reports.

Kohou missed the entirety of the 2025 campaign after suffering a partially torn ACL during training camp last summer. He was medically cleared for all football activities earlier this month and should have a relatively normal offseason. The Chiefs badly needed the cornerback help after losing both Trent McDuffie and Jaylen Watson to the Rams this week.

Atwell is signing a one-year contract with the Dolphins, Adam Schefter of ESPN reports Thursday.

Atwell had 1,535 receiving yards and five touchdown catches in five regular seasons with the Rams. The Miami native should help the Dolphins stretch the field with his speed. Atwell joins a wide receiver room that doesn't have much depth behind Jaylen Waddle (ribs), as no wide receiver besides Waddle (910) exceeded 317 receiving yards for Miami in 2025.
