Carradine, 28, is a former second-round pick of the 49ers back in 2013. He was in the final year of his four-year, $4.948 million rookie contract when he and San Francisco agreed to a one-year contract extension before the start of the 2016 season.
Carradine made a base salary of $1.1 million in 2017 before signing on with the Raiders back in March. Oakland decided to move on from Carradine after he requested his release.
The Cardinals, Saints, Lions and Patriots have all worked him out since becoming available.
In 2018, Carradine has appeared in one game for the Raiders and recorded one tackle and no sacks.
