Oakland Raiders wide receiver Antonio Brown initiated the discussion with general manager Mike Mayock midway through practice on Wednesday, resulting in the confrontation where disparaging language was used by Brown and sparked the team's current impasse with the player, according to a team source.
A Raiders source confirmed Brown was unhappy with the fine levied by the team and, seeing Mayock watching practice, walked over and initiated an exchange with the GM. The Raiders source confirmed information from another league source who said Brown called Mayock a "cracker" and unleashed a barrage of "cuss words" during the altercation.
