WEST YELLOWSTONE, Mont. (CBS Seattle/AP) — Officials in Yellowstone National Park say a Massachusetts man was gored by a bull bison that threw him 10 feet in the air and then pinned him to the ground.

The man, who is in his mid-50s, suffered a broken collarbone, shoulder blade, several ribs and a groin injury in Saturday’s encounter near the Norris campground. He was airlifted to an Idaho Falls, Idaho hospital and is expected to recover. His name was not released.

Park officials say the man was not taunting the animal, but let the bull approach within a few feet of where he was sitting and refused to move away.

Park rules require visitors to stay at least 100 yards away from bears and wolves and at least 25 yards away from all other animals. If an animal approaches, it is the visitor’s responsibility to move a safe distance away.

“Park visitors are reminded that wildlife in Yellowstone is, in fact, wild,” Yellowstone National Park said in a statement to KTVM-TV. “Intentionally approaching or disturbing animals is a violation of park regulations, which could ultimately lead to the death of the animal involved.”
