Official Weigh-in: Anderson Silva 186 vs Nick Diaz 185

One of the biggest sports weekends of the year will see the return of one of the biggest names in mixed martial arts, as UFC® legend and former middleweight champion Anderson Silva makes his return to the Octagon® to face one of the most dangerous strikers in the sport, former STRIKEFORCE® welterweight champion Nick Diaz, on Saturday, Jan. 31 at the MGM Grand Garden Arena in Las Vegas.

Widely considered the greatest mixed martial artist in history, Silva (33-6, fighting out of Curitiba, Brazil), will make his return after a devastating leg injury that sidelined him for more than a year. In his way will be the enigmatic Stockton bad boy Diaz (27-9-1, fighting out of Stockton, Calif.), who has been asking for a showdown with the “The Spider” for years. This 185-pound superfight is sure to be one of the best fights of 2015.
