Heath, 29, wound up signing on with the Cowboys as an undrafted free agent out of Saginaw Valley back in 2013. He managed to make the 53-man roster as a special teams contributor and a backup safety in each of his first three years in the league before signing a four-year extension with Dallas.
The Raiders signed him to a two-year, $8 million deal back in March of last year.
According to OverTheCap.com, releasing Heath creates $3.15 million in cap space and no dead money.
In 2020, Heath appeared in 12 games and recorded 33 total tackles, one tackle for loss, three interceptions, and three pass defenses.
