Sorry, but of course you can. The cheating KC player had no right to run into Henry. We know he did that because he bounced off and held his face. He didn't trip over a so called "outstretched leg". Henry had as much right to be in that place as the other guy - he had to run around him. I don't see Henry at fault on this one at all. If you were right, then it would be called obstruction every time a player shepherds a ball out for a goal kick. Similar principle
