Mitchell did not play in 2004 after not being signed in the free agent pool. Mitchell, the league's all-time kick return yardage leader, also played for Philadelphia (2000-02) and the New York Giants (2003). The most productive of his 14 seasons came as a Redskin.
"My 10 years here were great," he said. "When I left, I tried to do the same things wherever I went because it didn't make a difference what uniform I put on -- I was always going to be the same person and that's a person who goes out and gives his all."
Mitchell was a fifth-round draft pick in 1990 out of Southwestern Louisiana.
He has 13 career league records. Only Mitchell and Jim Brown have ever led the NFL in combined yards in a season four times.
