The Oakland Raiders are meeting with free-agent defensive backs Curtis Riley and Tyler Patmon on Wednesday, according to Ian Rapoport of NFL Network.

Riley spent the 2018 campaign playing safety for the New York Giants. He started all 16 games and registered 75 tackles, four interceptions, five passes defended and a defensive touchdown.

The 26-year-old, who played his collegiate football at Fresno State University, went undrafted but eventually landed with the Tennessee Titans in 2015.

He did not play in a single game for the Titans that ensuing season, and in 2016, he played in just four games, failing to log a statistic. He then appeared in seven contests with the team the following year, totaling 11 tackles and a pick.

Patmon resided with the Jacksonville Jaguars this past year, participating in 12 games and tallying 14 tackles.

The 28-year-old played his collegiate football at Oklahoma State University and went undrafted. He then ended up signing with the Dallas Cowboys in May 2014.

Patmon ultimately played in 11 games for the Cowboys during his first season, finishing with 11 tackles, an interception and a defensive score. Then, the following season, Patmon appeared in 11 contests for Dallas before being cut. He went on to sign with the Miami Dolphins and played in two games. Overall, he recorded 12 tackles and six passes defended.

The Round Rock, Tx. native was out of football in 2016 before landing with the Jaguars, where he played in 13 games in 2017 and logged four tackles.

The Raiders are coming off of a 2018 campaign in which they won just four games.
