Barton was waived by the Raiders on Saturday, Tom Pelissero of NFL Network reports.
Barton served as depth along the offensive line and was cut so the Raiders could add additional options in the secondary with both Rock Ya-Sin (knee) and Sam Webb (hamstring) questionable for a Week 4 matchup against the Broncos. Barton will be subject to waivers, so he won't be free to sign elsewhere unless he goes unclaimed.
