Day 11 of the 2012 Olympics in London is a day defending weightlifting gold medalist Matthias Steiner will never forget. Reason being, Steiner dropped a 432-pound barbell on his head, but was able to walk away from the accident.The German was attempting to snatch 196 kg when his knees and arms buckled, causing the massive weight to fall on top of his head. The medical staff on-hand immediately rushed to his aid, but luckily the weightlifter was not seriously injured. He did walk away from this freak accident under his own power and was taken to a local medical facility. Steiner did not return to the competition.
