Like any sport, jousting does have the risk of injuring the players. Unlike most sports, jousting has no defense because you are going to get hit and there is nothing you can do to stop it. As a result of this, injuries were quite common back in the day. For example, Henry VIII had at least two known jousting accidents. In the first accident, he forgot to lower his visor and he was struck in the head, which gave him a concussion. In the second accident, his horse collapsed on top of his leg, which crushed it and left him in a constant state of debilitating pain for the rest of his life. Another example of a jousting accident was when King Henry II of France was killed in the very tournament he was hosting. In the epic tournament in my second fantasy book, I am thinking of keeping it authentic and include some jousting accidents.
