Pelissero adds that Bethea is still owed $4.25 million for the 2018 season.
Bethea, 33, is a former sixth-round pick of the Colts back in 2006. He spent eight years in Indianapolis before signing a four-year, $21 million contract with the 49ers back in 2014.
Bethea was set to make a base salary of $5.25 million for the 2017 season when the 49ers released him during the offseason. The Cardinals later signed him to a three-year, $12.75 million contract last year.
The Cardinals are set to pay Bethea base salaries of $3 million over the final two years of the agreement.
In 2017, Bethea appeared in 15 games for the Cardinals and recorded 57 tackles, one sack, five interceptions, a forced fumble, and nine pass defenses.
