Abdullah has signed a contract with the Raiders.
In 17 games (11 with the Panthers and six with the Vikings) last season, the 2015 second-rounder recorded 51 carries for 166 yards and 38 catches for 289 yards with one TD. He'll provide the Raiders -- who've also added Brandon Bolden in free agency -- with further running back depth behind Josh Jacobs and Kenyan Drake, while also giving the team another option as a kick returner.
