San Francisco 49ers linebacker Aldon Smith, above, learns how to punch from MMA fighter Daniel Cormier during an MMA practice session at the American Kickboxing Academy on Feb. 15, 2013. Smith's preparation for another Super Bowl run is underway. On Friday, he began learning mixed martial arts moves with two-time Olympic wrestler Cormier with AKA wrestling club in San Jose. Smith plans on continuing to train there throughout the off-season as he prepares for his third season with the 49ers. He set a franchise record 19 1/2 sacks last season as the 49ers reached Super Bowl XLVII, where they lost to the Baltimore Ravens 34-31 on Feb. 3. (Dai Sugano/Staff) (Dai Sugano)
