Ogunbowale was released by Las Vegas on Sunday, Tom Pelissero of NFL Network reports.
After signing with the Raiders earlier in August, Ogunbowale has failed to make the 53-man roster. The veteran running back had been competing for a depth role, but it looks like the Raiders are content to roll with the younger Mike Washington and Dylan Laube as their backfield depth options behind Ashton Jeanty (ankle), even with Jeanty's status for Week 1 still uncertain.
