function not found The UFC middleweight championship changed hands for the first time in seven years when Chris Weidman upset Anderson Silva at UFC 162 on July 6. The talk about the fight has not waned in the days following the fight. While UFC president Dana White and new champion Chris Weidman both proclaimed that Anderson Silva could have an immediate rematch if he wanted it, the former champion took a step back to think about it. The pondering was short-lived, however, as White announced on Saturday’s edition of ESPN SportsCenter that Silva has agreed to rematch Weidman at the promotion’s monster year-end event in Las Vegas, UFC 168. Not only will Weidman vs. Silva II headline UFC 168 on Dec.
