What prompted former UFC middleweight champion Anderson Silva to quickly change his tune about a rematch with new titleholder Chris Weidman ? A little mental clarity. Silva suffered a shocking second-round TKO loss to Weidman on July 6 at UFC 162. Immediately after the pay-per-view loss, which snapped Silva’s 17-fight win streak and his string of 10 consecutive UFC title defenses, the 38-year-old said he didn’t want a rematch and was done with title fights. However, UFC President Dana White quickly promised the rematch would happen, and a week later, Weidman (10-0 MMA, 6-0 UFC) vs. Silva (33-5 MMA, 16-1 UFC) II was booked UFC 168 on Dec. 28.
