Richardson, 27, is a former seventh-round pick of the Rams back in 2012. He spent two years in St. Louis before he was waived and later claimed by the Jets, but was unfortunately among the team’s early roster cuts.
The Texans signed Richardson in 2015 and was on and off of their practice squad for most of the year before being waived and later signed to the Browns’ practice squad.
The Steelers signed Richardson to a future/reserve contract with the Steelers last year, and he was on and off of their active roster before being claimed by the Jaguars.
In 2016, Richardson appeared in three games and ran for seven yards on two carries to go along with no touchdowns.
