Mitchell was waived by the Chiefs on Saturday.
The 27-year-old from Louisiana signed a one-year deal worth up to $3.5 million with the Chiefs this past offseason but appeared in just one game prior to being waived. Mitchell has played in 28 regular-season games since being drafted in 2021, rushing for 1,523 yards and nine touchdowns. In a corresponding move, Kansas City signed Dameon Pierce to its active roster Saturday.
