Rapoport says Riley took a physical for Pittsburgh today, and it appears as though everything checked out.
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 joined the Raiders last year on a one-year contract.
In 2019, Riley appeared in all 16 games for the Raiders and recorded 34 tackles, no interceptions, a fumble forced and a pass defense.
