The Rams waived Kelly on Friday, Stu Jackson of the team's official site reports.
A sixth-round selection by the Rams in 2018, Kelly has made just eight appearances through two pro seasons and oscillated between the 53-man roster and practice squad. Overall, he averaged 2.8 yards on 30 carries and hauled in two of three targets for 27 yards. Considering how the team has approached Kelly to date, he likely will be signed to the practice squad if he clears waivers.
