The Raiders have signed several older, stopgap linebackers in recent years. Many of them haven't worked out.
Add Brandon Marshall to the list.
The Raiders released him Friday morning in a surprise move. ESPN's Adam Schefter was first to report the news.
Marshall appeared to confirm the news on social media following Schefter's report.
I thank Oakland for the Opportunity! Unfortunately I had to use training camp to work myself back to full health, and I did just that! Ready for what God has for me next 🙌🏾— Brandon Marshall (@BMarshh) August 30, 2019
He also said that he's fully healthy, a message he wants out there to get a job with another team this season. Marshall worked with the first unit most of camp, and was expected to be a regular in the base defense alongside Vontaze Burfict and Tahir Whitehead.
Marshall played a ton in the preseason, including a game in Winnipeg on an 80-yard field played without impact players. Head coach Jon Gruden was asked several times about Marshall's high snap count, and said he wanted to see the veteran get in a rhythm after regaining full health. He has battled knee issues since last season.
Marshall signed with the Raiders this offseason after spending the last six seasons with the Broncos.
His release appears to open the door for former fifth-round pick Marquel Lee, who has been a backup at both outside linebacker spots throughout camp.
Another player whose odds at making the roster just improved is Jason Cabinda, who was featured extensively on the penultimate episode of "Hard Knocks" last Tuesday night.

Final 53-man rosters across the NFL must be finalized by Saturday at 1 p.m. PT, so expect a lot more cut announcements over the next 24 hours.
