Appeared to me the issues began at about the 18 second mark. . .hard chops to the back of the head and neck by both wrestlers. . .very physical. The drop to the back of the knee was unnecessary and the arm chops should have been warned. The flurry going out-of-bounds was not pushing. . black singlet was on the verge of throwing punches. There were things done earlier in the clip by both wrestlers that should have been warned, even penalized. Imo, a DQ was not appropriate.
