If you watch the film of the Johnson/Ketchel fight you can see Johnson holding Ketchel up several times after he hit him with some good punches. Supposedly the fight was rigged so both fighters would get a big pay day. Ketchel apparently went off the script and tried to KO Johnson with a big punch that caused Johnson to go down. When Johnson got back up Ketchel rushed in and got knocked cold. It's pretty eeiry watching Johnson brushing Ketchel's teeth out of his glove.
