The Facts: The Raiders released Martin, a source tells NFL Network's Tom Pelissero.

Diehards Line:Martin led the Raiders in rushing yards last season, but appeared set to move on without him until Isaiah Crowell tore his Achilles during offseason workouts. Martin returned to the team and talked up his interest in mentoring first-round pick Josh Jacobs, but it appears the Raiders believe the rookie will be fine without that kind of tutelage. Jacobs now has Jalen Richard, DeAndre Washington, James Butler and Mack Brown behind him on the depth chart. Richard and Washington return from last season and seem to be the likeliest to remain on hand into the regular season.
