Holmes returns for his second season with the Raiders after playing in 16 games with one start in 2024 and recording 30 tackles (14 solo), one sack, two tackles for loss and three passes defensed.
"I'm going on Year 10, so I've been blessed to be able to experience the positive and the negative with it. But you know one thing about me, I'm going to set that tone," Roberts said.
Stokes spent the past four seasons with the Green Bay Packers (2021-24) after being drafted by the club in the first round (29th overall) of the 2021 NFL Draft.
Roberts enters his 10th season in the NFL and has played in 140 career games with 105 starts for the New England Patriots (2016-19), Miami Dolphins (2020-22) and Pittsburgh Steelers (2023-24).
