Fancy meeting you here! UFC middleweight champion Chris Weidman was on location at the Arnold Sports Festival and Fitness Expo in Columbus, Ohio (via Instagram), and just so happened to run into UFC 173 opponent Lyoto Machida. Sorry fight fans, no bad blood here, just mutual respect. But don't expect all those high-fives and bro hugs to last once the cage door shuts on May 24 in Las Vegas. See more on their upcoming title fight here.
