Sanders was also suspended for the first four games of the 2014 season for violating the NFL's substance-abuse policy.
The Jaguars released Sanders on July 17.
After Sanders returned from his four-game suspension, he never figured prominently into a receiver rotation that included second-round picks Allen Robinson and Marqise Lee and undrafted rookie Allen Hurns, who ended up leading the Jaguars in receiving yards (677) and receiving touchdowns (six).
Sanders caught just six passes for 55 yards.
He was drafted in 2013 primarily as a punt returner but was forced into significant action at receiver as a rookie because of injuries. He ended up with 51 catches for 484 yards and a touchdown.
