The Raiders continued their ultra-aggressive remodeling of the roster Monday, adding some much-needed depth in the middle of their defensive line by signing former Broncos, Falcons, Browns and Seahawks nose tackle Ahtyba Rubin Monday, per NFL Media’s Ian Rapoport.

Rubin began his career with Cleveland in 2008 as a sixth-round selection who was expected to have to fight for reps as a professional. But the 6-foot-2, 321-pound Rubin was able to make an immediate impact as a rookie, appearing in 11 games and forcing one fumble.

The Browns would then go on to award Rubin the starting NT job in 2010, and he rewarded the team by amassing an astounding 82 tackles (57 solo) and two sacks. Rubin would remain a starter for Cleveland through 2014 before he moved on to the Seahawks for the 2015-16 seasons, where he would amass three sacks while starting 32 games.

The 2017 season saw Rubin’s usage and production wane as he spent 10 games with the Falcons and two with the Broncos, amassing a total of just 15 tackles (seven solo).
