In October 2002, Owens was involved in another high-profile incident during a 49ers game against the Seattle Seahawks. When he scored the game-winning touchdown, he pulled a Sharpie magic marker from his sock, autographed the football, and delivered it to his financial advisor, who was watching from the stands. The signature is now worth over $100,000. Owens has also been involved in several other incidents since then. In April 2003, he took part in an exhibition game between the Dallas Cowboys and San Francisco 49ers and threw two touchdowns passes. However, he was later identified by team officials as having used a magic marker instead of a regular ball during the game. The NFL banned him for one season beginning in January 2004. In September 2005, Owens was arrested for public intoxication after an altercation with police officers in Dallas. He was also found to have cocaine in his system at the time of his arrest. In November 2007, Owens was suspended for three games without pay for violating the league's substance abuse policy. It was reported that he had tested positive for marijuana use on four occasions from June to September 2007. On February 5, 2008, it was announced that Owens would be allowed to return to play after serving a one-year ban. But just two days later, he was accused of assaulting his ex-wife, Nicole, outside a Los Angeles nightclub.
