The 30-year-old Roberts joins a Jets wide receivers corps that includes new acquisition Terrelle Pryor, Robby Anderson, Jermaine Kearse and Quincy Enunwa.

--Tight end Martellus Bennett is calling it a career after 10 seasons in the NFL.
Bennett, who was a free agent, announced his retirement via a posting on his Twitter account.
"I've decided to move on from the world of football and into the fantastical and wondrous world of creativity. I'm beginning what I believe to be my life's work @ImaginationAgcy," Bennett wrote

A Texas grand jury on Friday indicted Bennett on a felony charge of injury to the elderly related to an incident at NRG Stadium following Super Bowl LI, according to the office of the district attorney of Harris County, Texas.
Bennett was attending Super Bowl LI to watch his brother, Martellus, who was then a member of the New England Patriots. The Patriots rallied from a 25-point deficit to defeat the Atlanta Falcons, prompting Bennett to want to celebrate with his brother.
NRG security personnel, including a 66-year-old paraplegic woman, told Michael Bennett he had to use a different entrance for access when he attempted to push his way onto the field.
