Tempers erupted into a scuffle between Pro Bowl defensive tackle Darnell Dockett and offensive tackle Levi Brown in the Cardinals' second practice of the day Monday. Arizona newcomer Joey Porter also got in the face of fellow outside linebacker Cody Brown for putting up with tight end Stephen Spach repeatedly grabbing Brown's facemask in the drills. It was the first practice in full pads for the Cardinals and the third straight workout forced by rain indoors to the Northern Arizona University's domed stadium.
