Cyprien, a 2013 second-round pick by the Jaguars, started four years in Jacksonville recording 449 tackles, two sacks and four quarterback hits.
Following his four-year stint in Jacksonville, Cyprien signed with the Tennessee Titans (2017) and the Philadelphia Eagles (2019). During his brief time in Nashville, Cyprien started 10 games.
Riley was drafted by the Falcons in the third round of the 2017 NFL Draft out of LSU. In three seasons with the Falcons, Riley has played in 32 games and logged 84 tackles.
This move comes after the Falcons placed Keanu Neal on injured reserve as he injured his Achilles in Week 3 and will not return this season.
