Marshall (knee) was waived Wednesday after agreeing to an injury settlement with the Redskins, John Keim of ESPN.com reports.
Marshall showed promise in practices at times during his two seasons in the organization, but the running back has yet to make his NFL debut after landing on injured reserve in both 2016 and 2017. There's no timeline for when he's expected to be fully recovered from the torn patellar tendon he suffered last July.
Marshall (knee) didn't participate in mandatory minicamp, Kareem Copeland of The Washington Post reports.
Marshall went down early in training camp last year with a torn patella tendon, one of the worst possible injuries for a football player. He lit up the 2016 combine with a 4.31 40-yard dash at 219 pounds, but the sixth-round pick struggled to stay healthy in college and hasn't fared any better in the NFL. His last productive season was his freshman campaign at Georgia in 2012. Even if he eventually gets healthy, Marshall will be an extreme long shot to make the 53-man roster among a deep group of running backs in Washington.
