According Chacon, he was in the lunch room after batting practice when Cooper asked him to join him in his office.
"And I said, 'what do you want to speak to me about?'" Chacon said. "He said, ‘we just want to talk to you.’ I said, ‘anything you can say you can say to me right here. I don’t want to go to the office. He looked at me and I said there’s nothing for me to say to you guys.’ And I don’t think whatever they had to say to me they were going to make me happy. I didn’t want to get in a closed-room conversation. I just wanted to be left alone.
"I sat down to eat and Ed Wade came to me and very sternly said, ‘you need to come with me to the office.’ I said ‘for what?’ I said 'I don’t want to go to the office with you and Cooper.’ And I said ‘You can tell me whatever you got to tell me right here.’ He’s like, ‘oh, you want me to tell you right here?' And I said, ‘yeah.’ I’m not yelling. I’m calm."
It deteriorated quickly afterward, according to Chacon.
"He started yelling and cussing," Chacon said of Wade. "I’m sitting there and I said to him very calmly, ‘Ed, you need to stop yelling me. Then I stood up and said 'you better stop yelling at me.' I stood up. He continued and was basically yelling and stuff and was like, ‘You need to (expletive) look in the mirror.’ So at that point I lost my cool and I grabbed him by the neck and threw him to the ground. I jumped on top of him because at that point I wanted to beat his (butt). Words were exchanged."
Players quickly intervened to separate Wade and Chacon, who remembers being pulled away by backup outfielder Reggie Abercrombie.
