Longtime Raiders senior executive John Herrera has parted ways with the team, the Oakland Tribune reported Thursday.

Citing a source familiar with the situation, the newspaper said the decision was made by the business side of the organization, not by new GM Reggie McKenzie or new coach Dennis Allen. The Tribune was unable to reach Herrera for comment, and the Raiders had no comment.

Herrera joined the team out of high school, initially running errands for owner Al Davis, and he gradually moved up in the organization. He left the Raiders for stints in the Buccaneers' front office and as general manager of the CFL's Saskatchewan Roughriders before returning to Oakland in 1985.

Herrera served as the team's spokesman for a period during his long tenure in the Raiders' front office, and he was fiercely loyal to Davis, who died Oct. 8.

Meanwhile, longtime Raiders employee Willie Brown, who had been in charge of "squad development" and also helped the coaching staff, will remain with the team in a "redefined" role, according to the newspaper.
