LAS VEGAS – When you’ve been in the MMA game as long as Robbie Lawler has, a lot of things probably are second nature. Over a fighting career that lasted nearly a quarter-century as a pro, Lawler no doubt has sharpened plenty of his instincts. Saturday at T-Mobile Arena in Las Vegas, sitting cageside as a guest of the UFC, the promotion for which he once was welterweight champion, Lawler has a suspicion he might have been asked there for an announcement. “I had a feel for it. I just did,” Lawler said Saturday after his summer induction into the UFC Hall of Fame’s Modern Wing was announced.
