The Raiders have parted ways with senior executive John Herrera, who has served the organization as a spokesman and in a front office capacity for the better part of his adult life.
Herrera described it as a ``mutual, amicable deal on both sides'' in a phone interview.
According to someone familiar with the situation, the decision was made on the business side of the Oakland operation, and not by general manager Reggie McKenzie or coach Dennis Allen.
Herrera was hired by late owner Al Davis out of high school and has worked in almost every area of the organization.
``It's been something I've been thinking about since Al passed away last October,'' Herrera said. ``I had a great run. I was there 35 years, with there different tours of duty. I was involved in three Super Bowls, had an unbelievably great relationship with the owner and his family since I was a kid in 1963.''
The first clue Herrera's role had changed came Wednesday, when McKenzie held an off-the-record meeting with an informal lunch with Bay Area beat writers, and Herrera was not in attendance.
Herrera joined the Raiders out of Skyline High School in Oakland and eventually moved up in the operation, leaving for stints with the Tampa Bay Buccaneers and as a general manager in the Canadian Football League but eventually returning in 1985.
He was known as a fierce defender of Davis, which prompted the occasional run-in with writers covering the team, most notably a confrontation with San Jose Mercury News columnist Tim Kawakami that was caught on film and became a popular YouTube stop.
Since Davis died on Oct. 8, and the transfer of power went to son Mark Davis and his general manager McKenzie, Herrera's departure is likely to be only one of several moves as the organization is restructured.
``How can I be upset?,'' Herrera said. ``My experience here was way beyond anything I could have ever expected.''
A source familiar with the situation said Hall of Fame cornerback Willie Brown, a longtime Raiders employee who has been in charge of ``squad development'' and has assisted coaches, will remain with the team, but his role is being ``redefined.''
In other news, the Raiders have signed Brandon Underwood, a defensive back who last played for the Green Bay Packers. He was a sixth-round draft pick by Green Bay in 2009, where McKenzie worked in the personnel department.
Underwood's time with the Packers was marred by off-the-field issues, with two arrests in domestic disputes. He played in 23 games in two years, mostly on special teams.
