Riley, 28, wound up signing on with the Titans as an undrafted free agent out of Fresno State back in 2015. He was on and off of their roster for two years before signing on with the Giants in 2018.
Riley finished out a one-year deal with the Raiders in 2019 and had signed a one-year deal with the Steelers in 2020 before being released and re-signed to the practice squad. The Cardinals signed him last month and he has bounced on and off their practice squad this season.
In 2020, Riley has appeared in four games for the Cardinals and recorded nine tackles and no interceptions.
