After suffering a serious brain injury, Jeff Sperbeck was put on life support, according to a TMZ report on Wednesday. Doctors could only keep him alive long enough to allow for organ donation. The site also mentioned that after Sperbeck fell from the golf cart, John Elway was the one who called 911 first. In addition to being Jeff Sperbeck’s longstanding buddy, the 64-year-old NFL star and former general manager of the Denver Broncos, John Elway, was also his business partner.

During the course of his playing career, Sperbeck had played for Elway. When Sperbeck signed on as Elway’s agent during his NFL career in 1990, their working relationship officially began. Their relationship developed into a close friendship and fruitful business partnership over time.
