The Raiders added more veteran depth to their mix by signing a pair of defensive linemen.
Defensive tackle Ahtyba Rubin has joined the Silver and Black, his agency announced on Monday afternoon.
Rubin isn't the only new guy coming to the Raiders. They also signed former Arizona defensive end Frostee Rucker, according to ESPN, a 13th-year pro who spent his first six seasons in Cincinnati while current Raiders defensive coordinator Paul Guenther was on staff.
Rucker is 6-foot-3, 284 pounds and will turn 35 in September. He has been a full-time start but four times, though he made 16 starts in 2017 .
Rubin stands 6-foot-2, 310 pounds and has 107 starts to his credit over 10 seasons. He will turn 32 in July.
Rubin is an interior defensive lineman known primarily as a nose tackle, will join a veteran mix that features several players over 30 years old, and has experience learning new systems.
Rubin played seven seasons with the Browns, two with the Seahawks and spent the 2017 regular season with Denver and Atlanta.
He has 15 sacks, two interceptions and six forced fumbles in his career. He's known primarily for run defense, and could offer rotational depth inside behind Justin Ellis should he make the 53-man roster.
Rucker has never had more than five sacks in a season. He has 21 in his career, to go along with eight forced fumbles.
Both guys will challenge for a spot in the defensive line rotation.
The Raiders did not immediate announce either move, so the corresponding moves are not yet known.
