The Panthers have agreed to terms with free agent offensive tackle Stone Forsythe, Jeremy Fowler of ESPN reports.
Forsythe was in Seattle for two seasons with Panthers head coach Dave Canales.
The Seahawks drafted Forsythe in the sixth round in 2021, and he spent his first four seasons in Seattle. He played 53 games with 14 starts.
He began last season with the Giants before joining the Raiders for the start of the season. Forsythe’s 13 starts last season were a career-high.
He has appeared in 70 games with 27 starts in his five seasons in the league.
The Panthers will be without Ikem Ekwonu at the start of the season as he works his way back from a torn patellar tendon. Backup tackle Yosh Nijman is a free agent.
The Panthers lost free agent center Cade Mays on Monday when he agreed to a deal with the Lions. They replaced Mays on Tuesday by agreeing to terms on a one-year deal worth up to $4.75 million with Luke Fortner, Tom Pelissero of NFL Media reports.
Fortner, who turns 28 in May, played last season in New Orleans after a trade from Jacksonville on Aug. 17. He had taken a pay cut to remain with the Jaguars before the trade.
He entered the NFL as a third-round pick of the Jaguars in 2022, and he started every game for the team in his first two seasons. Fortner, though, made no starts in 2024.
In New Orleans, he played all 17 games, with 10 starts.
The Panthers confirmed reports that they have re-signed Isaiah Simmons on Tuesday afternoon and they also announced deals with two other players from their 2025 roster.
Wide receiver David Moore and linebacker Thomas Incoom will both remain with the team. No terms were announced for either deal.
Moore had 32 catches for 351 yards and three touchdowns for Carolina during the 2024 season, but he missed most of last year with an elbow injury. He had one catch for five yards in four regular season games before landing on injured reserve.
Incoom had 25 tackles in 25 games while appearing almost exclusively on special teams the last two seasons.
The Panthers also waived defensive tackle Popo Aumavae.
The Panthers are keeping a former first-round pick in their building.
Per a report from NFL Media, Carolina has agreed to re-sign safety Isaiah Simmons.
Terms of the deal were not immediately disclosed.
Simmons joined the Panthers in late November on the team’s practice squad. He was later signed to the 53-man roster and blocked a punt in the postseason loss to the Rams.
Simmons had spent 2025 training camp with the Packers but was let go during roster cuts.
The No. 8 overall pick of the 2020 draft, Simmons played his first three seasons with the Cardinals before being traded to the Giants during training camp in 2023.
He has appeared in 89 career games with 42 starts, recording five interceptions, 21 passes defensed, nine forced fumbles, and 8.5 sacks.
The Panthers are parting ways with a veteran defensive lineman.
The team announced the release of defensive tackle A’Shawn Robinson on Tuesday afternoon. Robinson had one year left on his contract in Carolina.
Robinson’s departure will clear a little more than $10 million in cap space for the coming season. They will retain a little over $2 million in dead money as well.
Robinson played in 33 games over the last two seasons. He had 145 tackles, eight sacks, a forced fumble and a fumble recovery in that action and he also had three tackles in the playoffs last season.
Derrick Brown, Tershawn Wharton, Bobby Brown, and Cam Jackson remain on hand at defensive tackle.
