Raiders running back Isaiah Crowell tore his Achilles during a workout with the team Monday and is out for the season, according to a report from ESPN NFL insider Adam Schefter. Crowell signed a one-year deal with the Raiders earlier in the offseason.

Fantasy Impact

Crowell's injury will put added pressure on rookie running back Josh Jacobs, who was just drafted by the Raiders in the first round of last week's NFL Draft. Jacobs now has the inside track with little competition to be a three-down running back for the Raiders, with Jalen Richard likely serving as the occasional pass-catching back out of the backfield. Jacobs should be one of the first players off the boards in upcoming rookie dynasty drafts.
