The Broncos have been forced to train without fans present as construction continues on their training complex this off-season, but tempers flared recently.
"I don't like [fights], to tell you the truth. You don't do it in a game. If you do it in a game, it usually costs you something important, it costs you a drive, costs you field position. I'm into treating practice like a game. I'm not a fan of it," Manning said, ESPN reports.
Coach John Fox gathered all the players together in the middle of the field at the end of practice and revealed that he reminded them about keeping their emotions under control.
