<P> The Challenge of the Champions hadn't even been dreamed up at the time of Red Rock's retirement . Sometime in 1988, John Growney thought of a special match - up between the two 1987 Champions . It was decided that Lane and Red Rock would have 7 showdowns at different rodeos in states across the West . The event was titled the "Challenge of the Champions ." Red Rock was brought out of retirement and Lane Frost finally rode him to the eight - second whistle for a scoring ride for 4 of the 7 matches . </P> <P> In 1989, Lane Frost was competing in Cheyenne Frontier Days in July, the oldest and biggest outdoor rodeo in the world . He had just dismounted after a successful ride on the bull SO Takin' Care of Business . He landed down on his hands and knees in the mud . The bull turned and knocked him prone . Then the bull hit him with his right horn in the back as he lay on the ground . It broke some ribs and "it is assumed that the broken ribs severed a main artery". He died in the arena . After Lane's death, John was sure he didn't want another bull rider to sit on Red Rock . Red Rock would stay retired from the PRCA . However, John continued to let people visit Red Rock since he was so friendly and gentle, and even more famous after the Challenge of the Champions . John also took Red Rock to Lane's memorial service during the 1989 NFR in Las Vegas . </P> <P> The ProRodeo Hall of Fame simultaneously inducted both Lane and Red Rock the same year, in 1990, and John brought Red Rock to the induction ceremonies . At the time, Red Rock was only the third bull inducted since the hall opened in 1979 . Today, there are only 7 bulls inducted as of 2018 . </P> <P> On June 8, 1994, Red Rock suffered a stroke while living out his retirement on the Growney ranch in Red Bluff, California . He "died while the vet was attending to him". He was 18 years old . John buried him under an oak tree on the ranch in Red Bluff . Clyde Frost, Lane's father, commented "He was a great bull and he had a great life . I know he's in a better place now...but he had it pretty good here too ." </P>
