Further investigation is needed.  I wonder what happened.  The ball would not necessarily have hit her.  
I could have passed right behind her head - or in front. It could be going back-to-front or vice versa, although I think am seeing a slight blur suggesting side-to-side.
Perhaps I will retrace my steps and see if there is an answer after I am done chowing down.
Meanwhile, place your bets.  I say no.  No knock to the noggin.  Just a suggestive pic.
