Raiders-Cowboys practice gets heated

The joint practice between the Oakland Raiders and Dallas Cowboys went just about how the coaches scripted it Tuesday with high intensity in an emotional environment.

Then things went a bit over the line when a hard hit by Dallas cornerback Morris Claiborne on Oakland tight end Mychal Rivera led to a brawl that nearly spilled over into the stands and featured a Raiders fan swinging a helmet at a Cowboys player and cornerback B.W. Webb retaliating with a swing at the fan.

Webb called it a "dangerous situation" and says he doesn't know why fans would try to get involved.

Raiders coach Dennis Allen says he did not like the fight, but was pleased with the intensity of the practice.
