Magnuson, 26, originally signed on with the 49ers as an undrafted free agent out of Michigan back in 2017. He lasted just over two years in San Francisco before he was waived and later signed by the Bills.
The Raiders later signed Magnuson off of the Bills’ practice squad last year. Las Vegas ended up waiving him and he ended up on the practice squad.
Magnuson signed a futures deal with Las Vegas this past January.
In 2019, Magnuson was active for one game, but did not make a start.
