It sure seems like there have an inordinate number of DQs this week. Maybe its the same as always, but we are just noticing them because of the number of them involving US athletes?
But it sure seems like they are working overtime to find violations.
Saw the replay of the alleged violation. Only showed once and couldn't tell if he was pushed on to the line, but I am guessing he was which probably led to rescinding the violation. The official would have been watching the feet, not the torso.
