Field hockey players might wear skirts, but that doesn't mean they aren't tough. Check out New Zealand striker Katie Glynn here. She tries to knock the ball away from her opponent, but instead gets bonked on the noggin. Listen to the crowd let out a collective "oohhh" as it happens, and again as it is replayed twice. This is what Glynn looked like as she was helped off the field, and here she is after getting bandaged up. She was able to return to the game, but New Zealand lost to the Netherlands in a shootout.
