Stone signed a one-year contract with the Bills on Friday, NFL reporter Jordan Schultz reports.

Stone is coming off a career year in 2025 with the Bengals, when he logged a career-best 104 tackles (65 solo), including 2.0 sacks, and four pass defenses (one interception and one pick-six) across 17 regular-season games. He was a starting safety in each of his two years in Cincinnati, but Stone is not guaranteed to start in Buffalo, with his primary competition coming from Cole Bishop and C.J. Gardner-Johnson.

Campbell (ankle) and the Giants agreed to terms on a one-year contract Friday, Adam Schefter of ESPN reports.

Campbell will have a new home in New York with the Giants after spending the last five years of his NFL career with Miami. He mostly served on special teams in 2025 and logged five tackles (four solo) across 10 regular-season games. Campbell ended the season on injured reserve due to an ankle injury but should be available for offseason programming.

Treadwell and the Colts agreed to terms on a one-year contract Friday, James Boyd of The Athletic reports.

Treadwell opened the 2025 campaign on the Colts' practice squad before being signed to the active roster in early November. He was used almost exclusively on special teams and did not record a target across 10 regular-season games last year. Treadwell will likely reprise his role as a special teamer for the 2026 season.

Smith is expected to fill a complementary role alongside Emari Demercado behind Kenneth Walker in Kansas City's new-look backfield, Pete Sweeney of the Kansas City Star reports.

The Chiefs have parted ways with Isiah Pacheco and look unlikely to bring back Kareem Hunt, but Walker's expected to handle the bulk of the rushing workload after signing a three-year contract with the team, leaving Smith and the newly signed Demercado to compete for change-of-pace duties. Smith had 44 carries for 151 yards while adding 25 catches for 172 yards and a touchdown on 35 targets in 2025, showing some promising pass catching skills as a rookie seventh-round pick.

Tagovailoa officially signed his one-year, $1.3 million contract with the Falcons on Friday.

Falcons GM Ian Cunningham confirmed Friday that Tagovailoa will compete with Michael Penix (knee) for the starting quarterback role in Atlanta, per Marc Raimondi of ESPN.com. Both are oft-injured left-handed quarterbacks, but Tua is the healthier of the two at the moment, as he passed a physical in order to effectuate his contract with Atlanta while Penix is recovering from November surgery to repair a torn ACL. Penix has a chance to be ready for the start of the regular season, but Tagovailoa could have the early edge in Atlanta's QB competition while Penix works his way back into form.

Conklin is signing a one-year contract with the Lions, per his agent Mike McCartney.

Conklin is expected to compete for backup snaps with Brock Wright (neck) behind Sam LaPorta (back). After recording 1,622 receiving yards across three seasons with the Jets, the 30-year-old tight end posted just seven catches for 101 yards with the Chargers in the 2025 regular season.

The Panthers signed Walker to a one-year contract Friday, Ian Rapoport of NFL Network reports.

Walker has started 48 games across the last three regular seasons and operated as the Packers' left tackle during the 2025 campaign, playing all 1,057 of his offensive snaps at the position. He gives the Panthers a capable option should Ikem Ekwonu (knee) not be recovered from a torn patellar tendon that he suffered in Carolina's wild-card loss to the Rams in January.

The Colts signed Thomas (migraine) to a one-year contract Friday, James Boyd of The Athletic reports.

Thomas dealt with migraines for most of last season and was shut down in December after initially being placed on the reserve/non-football illness list in November. Thomas has appeared in 36 career regular-season contests and will serve in a depth role for the Colts.

The Cardinals re-signed Fehoko (wrist) to a one-year contract Friday, Josh Weinfuss of ESPN.com reports.

Fehoko suffered a season-ending wrist injury in Week 10 last season and missed the remainder of the 2025 campaign. A wide receiver by trade, Fehoko played just 37 offensive snaps across eight games but logged another 116 snaps on special teams. He'll compete for a roster spot this summer under new coach Mike LaFleur.

McMillian signed his one-year, $5.767 million restricted free agent tender Friday.

It represents a significant raise for McMillian, who made $1.03 million in 2025. The 25-year-old cornerback joined the Broncos as an undrafted free agent in 2022 and has carved out a prominent role in Denver's secondary. He appeared in all 17 regular-season games last season, making three starts, and recorded 56 tackles (40 solo), including a career-high 4.0 sacks, nine pass breakups, including two interceptions, and a pair of forced fumbles. He's the team's No. 1 slot corner.
