Raiders defensive coordinator Chuck Bresnahan and assistant coaches Greg Biekert, Rod Woodson and Kevin Ross have been fired, according to a report by 95.7 The Game's Chris Townsend.
Raiders Insider Paul Gutierrez has been in contact with the team and reports that no personnel decisions have been made as of late Tuesday. Senior executive John Herrera said "that's not right" in response to the report, when contacted by Comcast SportsNet California.
Oakland allowed 433 points in 2011, the second most in franchise history. Bresnahan was hired as defensive assistant by former owner Al Davis in the 2010 offseason then promoted to coordinator.
Last season Oakland posted franchise worsts in TD passes allowed (31), yards per carry (5.1), yards passing (4,262) and total yards (6,201).
On his weekly radio show on Sacramento's 1140 The Fan, Raiders head coach Hue Jackson discussed the situation, saying that any potential decisions involving assistant coaches would be made soon.
"If we are going to go in that direction, it would be soon because I think that would be only fair to the coach and his family," Jackson said.
