LAS VEGAS — Las Vegas will host the 2015 World Wrestling Championship in the first qualifier for what could be wrestling's final appearance as an Olympic sport in the 2016 Rio Games. The sport's governing body selected Las Vegas over bids from several other cities including Tehran, New Delhi, Panama City, and Sochi, site of the 2014 Winter Olympics. “Hosting the World Championships in Las Vegas is certainly a positive step forward in our quest to show the world the relevance of wrestling and help entrench our sport on the Olympic program,” Nenad Lalovic, acting president of the International Federation of Associated Wrestling Styles, said. — Reuters
