As a BMX rider, Yaeger gained the nickname "Crowbar" and acquired sponsors for his BMX riding, participating in tours and competing in events. As an actor, Yaeger auditioned for a Nickelodeon/Clear Channel Communications live tour based on the popular cartoon show Rocket Power. What he thought to be an acting role turned out to be an athletic/stunt role. On the first day of rehearsals, the director found out that his BMX talent was at a professional level and incorporated it into the show. The show briefly toured the US Midwest in spring 2002 before being canceled due to low ticket sales. After experiencing many BMX-related injuries, he decided to go back to college to pursue a master's degree in hydrogeology. In 2006, while attending school in San Francisco, he was in a motorbike crash that resulted in multiple injuries. He hit a pole and went over a 40-foot embankment, crashing on the side of the freeway. His left leg was amputated below the knee, his right anterior cruciate ligament and medial collateral ligament were torn, his pelvis was torn in half along with his bladder, seven vertebra were broken, his lungs collapsed, multiple ribs were broken, and he had a severe concussion. One year later, Yaeger made a full recovery, returning to his acting career. Career Yaeger started taking acting courses and began acquiring role after role. Some of his early work includes Michael Anderson's Tenderloin, a film about one of the most infamous neighborhoods in San Francisco. The film premiered at the Mill Valley Film Festival in October 2009. Yaeger also shares the joy of working on Dolphin Tale with Morgan Freeman, Ashley Judd and Harry Connick, Jr.; Knife Fight with Rob Lowe; War Flowers with Christina Ricci, Tom Berenger and Jason Gedrick; and the Syfy feature film Piranhaconda
