Raiders RB Isaiah Crowell tore his Achilles in a workout on Tuesday and will miss the entire 2019 campaign, ESPN's Adam Schefter reports. Crowell will hit free agency next offseason at 27 years old. First-round rookie RB Josh Jacobs was already the favorite to lead Oakland in touches this season. Crowell's absence only makes him a safer bet. Undersized pass-catchers Jalen Richard and DeAndre Washington, plus 2018 undrafted free agent Chris Warren, sit behind Jacobs on the depth chart.

ESPN's Adam Schefter reports that RB Marshawn Lynch "is not planning to play football again." That likely increases Oakland's focus on the position for this week's NFL Draft. The Raiders signed Isaiah Crowell in free agency to join a backfield that returns Jalen Richard, DeAndre Washington and 2018 rookie Chris Warren. Last year's carry leader, Doug Martin, remains on the open market. Richard ranked 3rd on last year's Raiders with just 55 rushing attempts but also tied for the team reception lead. Washington tallied only 31 total touches over 10 games and doesn't appear likely to be a significant factor. We'll see how/whether Oakland addresses the position in the draft before projecting others forward. Warren looks intriguing after a strong 2018 preseason, but adding an early-round RB this week would make him harder to like.

The Raiders have signed RB Isaiah Crowell to a 1-year contract. Crowell averaged 4.8 yards per carry in a wildly inconsistent 2018 with the Jets. He delivered 219 yards in a win over the Dolphins and racked up 102 and 2 TDs on just 10 carries in the surprise opening blowout win at Detroit. But Crowell cracked 50 yards just 1 other time and tallied only 143 rushing attempts (plus 21 catches) for the season. His arrival in Oakland likely means unrestricted free agent Doug Martin is done there. Marshawn Lynch isn't expected to decide until after the NFL Draft whether he'll return for another season. RBs Jalen Richard and Chris Warren remain on the roster. HC Jon Gruden has compared Richard to former RB Charlie Garner, which indicates he'll maintain a significant role. Warren spent his rookie season on IR after a flashy preseason. This backfield figures to see further changes before we can project its 2019 touch splits.
