@foxnews: Yellowstone officials have decided the fate of the bison that launched a grandfather eight feet into the air. The bull that seriously injured Carl Isom-McDaniel in last week's viral attack will not be euthanized and will remain in the park. Officials said they are taking "no management action" against the animal, according to TMZ. The grandfather suffered multiple broken bones that required surgery after the bison charged him. The shocking encounter, captured by wildlife photographer Mike MacLeod, went viral after the bull tossed Isom-McDaniel into the air before standing over him.
