Turned Professional: January 1990 at age 17. He forged his mother's signature on the Pro License applications to the ABA and NBL. His mother got wind of it a couple of months later (Purse had been doing quite well as a pro in the interim, including winning his first pro race. See "First Professional race result" below) and complained to both sanctions. She ordered that John to be suspended and prevented from racing pro since he did so without her permission. He found out when he went to sign up to race the NBL Memphis Indoor Classic in Memphis, Tennessee in March 1990. He had to sit out both days of racing. He got his pro papers in order in time to race the ABA Supernationals in El Paso, Texas. He won this last "A" pro race on Sunday (Day 2) April 1, 1990 and was moved up to "AA" pro.
