The Arizona Cardinals have been told repeatedly by head coach Bruce Arians: Cardinals don't fight Cardinals.
For the second time this week a scuffle broke out and coach Arians was having none of it.
The players were told to set their helmets down and they started running. Then ran some more.
Many sideline-to-sideline sprints ensued with an unhappy Arians watching.
"It's camp, stuff like that happens," cornerback Justin Bethel said. "We just have to know that we're a team and we have to stick together. We're trying to win a championship; we can't be fighting amongst each other. It's all about team. Team is what it takes -- that's our slogan right now.
"We just had to do some extra conditioning and put it behind us and move on to the next day and get ready for Minnesota."
Bethel added that Arians made his point about how much he did not want to see his players fight each other, which was one everyone already knew.
"Some guys, they lose their tempers and it happens," he said.
After the fight, it looked as if the team was unsure if practice had ended. A short time later the session resumed, with Arians and other coaches returning to the field to watch -- not instruct.
"I think it was just some of the players on the team just decided we wanted to finish up practice because every play is important for us in practice," Bethel said. "So we just decided, I think, they decided amongst themselves that let's go ahead and just finish out the practice because we didn't have that much left, so let's just go ahead and finish it out and get the looks in."
It's the team's last one of the week as they travel to Minnesota on Friday to play the Vikings in their second preseason game on Saturday.
