Cowser is taking reps on the defensive line throughout training camp, Vic Tafur of The Athletic reports.

EDGE Analysis

The Raiders had tried Cowser as a linebacker over the past few seasons, but he's slated to play defensive end throughout the preseason after primarily serving on special teams in 2017.

Cowser has signed a reserve/future contract with the Raiders, Matt Schneidman of The San Jose Mercury News reports.

EDGE Analysis

Cowser appeared in 22 games for Oakland between the 2016 and 2017 seasons, but the 28-year-old failed to make a single game appearance throughout 2018. It appears he'll now get another chance to earn a role in Oakland's linebacking corps, though Cowser's most probable outcome -- should he make the team out of training camp -- is likely contained to work on special teams.

Cowser was waived by the Raiders on Monday, Michael Gehlken of the Las Vegas Review-Journal reports.

EDGE Analysis

Cowser was waived by Oakland to begin the 2018 season, briefly rejoined the team in late October, and will ultimately be set loose once more to make room for Kony Ealy on the 53-man roster. If the depth defensive end goes unclaimed on waivers, he'll be a strong candidate to sign with the Raiders' practice squad.

Cowser was promoted from the practice squad to Oakland's active roster Tuesday.

EDGE Analysis

Cowser appeared in all 16 games for the Raiders in 2017, compiling 23 tackles and a forced fumble. He's spent most of the season on their practice squad.

Cowser was waived by the Raiders on Saturday, Michael Gehlken of the Las Vegas Review-Journal reports.

EDGE Analysis

Cowser cleared waivers Sunday and will be eligible for practice squad consideration, having played in all 16 games for the Raiders in 2017.

Cowser, an exclusive-rights free agent, signed a contract with the Raiders on Monday.

EDGE Analysis

Cowser signed with the Raiders as an undrafted free agent ahead of the 2016 season and has since racked up 32 tackles, one sack and one forced fumble in 22 games. The product of Southern Utah should remain a key special-teams player and depth linebacker for Oakland in 2018.

Cowser has been signed to the Raiders' active roster, Adam Caplan of ESPN reports.

EDGE Analysis

Cowser's signing will add depth to the Raiders' pass-rushing depth.
