Arkansas fired coach Bobby Petrino on Tuesday, saying he engaged in reckless behavior that included hiring his mistress and then intentionally misleading his bosses about everything from their relationship to her presence at the motorcycle accident that ultimately cost him his job. "He made the decision to mislead the public, (and it) adversely affected the university and the football program," athletic director Jeff Long said at an evening news conference, choking up at one point as he discussed telling players the news. There was a "pattern of misleading and manipulative behavior to deceive me."
