Perry Alphonso Riley Jr. is a former American football linebacker. He was drafted by the Washington Redskins in the fourth round of the 2010 NFL Draft. He played college football at LSU.

The 2010 Washington Redskins season was the franchise's 79th season in the National Football League (NFL), and their first under new head coach Mike Shanahan, who also began his term as the team's Vice President of Football Operations. The Redskins obtained the 4th pick in the 2010 NFL Draft as a result of their 4–12 record from their previous season, which they used to draft Oklahoma tackle Trent Williams. Finishing the season 6–10, the Redskins improved on their 4–12 record from the 2009 season, but were officially eliminated from postseason contention in Week 14. Of the 16 games of the season, only four were decided by more than a single possession.
