Ellis, 28, is a former fourth-round pick of the Raiders back in 2014. He played out the final year of his rookie contract and was set to be an unrestricted free agent for the first time in his career before agreeing to a three-year extension worth over $15 million last year.
The Raiders placed Ellis on injured reserve coming out of the preseason with a knee injury and cut him with an injury settlement.
Ellis has since worked out for the Lions and Chiefs.
In 2018, Ellis appeared in six games and recorded seven tackles and no sacks.
Davis, 27, was originally a third-round pick by the Ravens in the 2015 NFL Draft out of Iowa. He was in the third year of his four-year rookie contract when the Ravens waived him back in 2018.
Davis was claimed by the Browns the day after off of waivers and finished out the year in Cleveland. He re-signed in Cleveland on a one-year, $2 million deal but was released coming out of the preseason.
From there, David has a brief stint with the Colts.
In 2018, Davis appeared in five games for the Browns and recorded one tackle and no sacks.
