Mike Garafolo of NFL Network noted it was a two-year deal that can be worth as much as $6.75 million with player and team incentives.
Rivera spent the first four seasons of his career with the Oakland Raiders.
Rivera entered the league as a sixth-round draft pick in 2013 out of Tennessee and caught four touchdowns as a rookie. He enjoyed a career season the following year with 534 receiving yards and four touchdowns, but his production fell off in 2015 and 2016 as tight end Clive Walford played a larger role in Oakland's aerial attack:

Marcedes Lewis is still on the Jacksonville roster, but he is 32 years old. What's more, his 169 receiving yards last year marked his lowest total since he was a rookie in 2006.
Rivera is only 26 years old and can take advantage of openings down the middle created by the additional defensive attention drawn by wide receivers Allen Robinson, Allen Hurns and Marqise Lee.
