http://www.MMAWeekly.com was on location at the UFC 148: Silva vs. Sonnen II weigh-ins in Las Vegas where things once again got heated between Anderson Silva and Chael Sonnen. So much so that Silva lost his cool and shoulder punched Sonnen in the jaw.It was also the final weigh-in for former UFC light heavyweight champion Tito Ortiz, who squares off with Forrest Griffin for the third and final time as he heads into retirement and the UFC Hall of Fame.
