After starring as a quarterback at Florida A&M, Riley was drafted by the Bengals as a defensive back in 1969. He spent his entire 15-year career with the team and finished with 65 interceptions, which ranks fifth on the all-time list. He picked off eight passes during his final season, earning him All-Pro honors for the first time in his career.
Bengals owner Mike Brown said Riley “had everyone’s respect” in a statement.
Following his retirement, Riley was an assistant coach with the Green Bay Packers for two seasons. He then returned to Florida A&M as the team’s head coach and compiled a 48-39-2 record. Once he was done coaching in 1993, Riley served as Florida A&M’s athletic director. He held that position until he retired in 2004.
Florida A&M inducted Riley into its Hall of Fame in 1977. Riley was also inducted into the Black College Football Hall of Fame in 2015.
