Ridley announced the news on his Instagram account.
“… To the Organization and city of NEW YORK I truly thank you for all the love,” Ridley, formerly of the Jets, wrote. “But now it’s on to Detroit for me! I can’t be happier for another shot to tote this pill and showcase the gifts I’ve been truly blessed with! Detroit, I’ve got a suprise [sic] for you this year, I promise. I’m ready to get to work with my new family, so April 18th can’t come soon enough! Let’s eat fellas, and this year we want the whole plate!!”
Ridley had just 90 yards on 36 carries last season in eight games. He was returning from an ACL injury.
Ridley spent his first four years with the New England Patriots and rushed for 1,263 yards and 12 touchdowns in 2012.
