Aldon Smith's once-worrisome left shoulder looked great as he made his foray into mixed martial arts training Friday, less than two weeks after the 49ers' Super Bowl defeat. "We lost the game, and that's why I'm here," Smith said at San Jose's American Kickboxing Academy. "You lose and you have two choices: You either complain about it or you train for next season." Smith, selected by his teammates as their MVP last season, sparred for nearly an hour with Daniel Cormier, a two-time Olympic wrestler and current UFC fighter.
