Teen rodeo champ Walker Smith is fighting for his life in a hospital after the 17-year-old bull rider was stopped by the raging animal, stomping on his chest and collapsing both his lungs.
The frightening accident happened last Friday when Smith -- the 2022 Junior Bull Riding Champion -- rode a bull at the Space Coast State Fair in Melbourne, Florida.
During his three-second ride, the bull bucked, sending the teenager to the ground ... when the 1,200+ pound bull trampled him.
