Read the rule again. Before you get to the 4 bullet points for targeting, it stipulates that it qualifies on a "Defenseless player." Then, any one of the 4 examples applies as targeting.Not according to that rule you cannot. Forceable contact to the head neck area with a shoulder, helmet, arm or fist..... Doesn't even have to be defenseless......... For the defense anyway.......
Edit: Going back to yesterday, I presume they didn't think the contact was forcible.
