Denver Broncos wideouts Emmanuel Sanders and Courtland Sutton got into a fight during Monday's practice and had to be separated multiple times.
According to reporters in attendance, the two exchanged heated words before Sanders lunged at Sutton.
Offensive lineman Ronald Leary, defensive end Derek Wolfe and other team-mates stepped in to separate the two, but Sanders and Sutton continued swinging punches and throwing water bottles before they were pulled apart.
Head coach Vic Fangio, who responded sternly to the only previous scuffle of training camp on July 25, called the team together and addressed the situation before practice resumed.
"I don't know all of the details of it," Fangio told reporters after practice. "It kind of happened about 10 minutes before I even found out about it because I was on the other side of the field. Obviously, it's not good. Can't happen, shouldn't happen, but you have to be able to react to these things and handle them the right way."
Asked by former Broncos wideout Brandon Stokley, now a Denver radio host, if the bad blood between Sanders and Sutton could linger, Fangio replied, "I don't think so."
"As you well know being an ex-receiver," he continued, "they're a bunch of divas in there at times. Hopefully, it's just a rare episode. If it continues, then I think it's a problem."
Sutton avoided the media after practice, and Sanders declined to comment, saying with a smile, "You guys know I'm not talking." Sutton was given a microphone by the team for Monday's practice, but no footage relating to the fight was released in a video posted to the team's site.
Sanders, 32, has been working back toward full participation after an Achilles tear in December. Sutton, 23, is entering his second season and expected to take a larger role.
