A Colorado man visiting Yellowstone National Park was attacked by a bison. It's the latest bison attack caught on camera. The man tried to rescue a child from the charging bison when the wild animal instead attacked him. Another man even jumped into harm's way to fend off the attack by spraying what appeared to be bear spray at the bison. The child was able to run back to safety. Officials say the man who was gored was taken to the hospital with a dislocated arm.
