Junior middleweight world titleholder Canelo Alvarez goes up in weight to face fellow Mexican Julio Cesar Chavez Jr. at a catchweight of 164.5 pounds Saturday night at the T-Mobile Arena in Las Vegas.

Alvarez (48-1-1, 34 KOs), who said he will campaign as a full-fledged 160-pound middleweight following his showdown with Chavez, hasn't lost a fight since dropping a majority decision against Floyd Mayweather in 2013 and enters the fight against Chavez as the favorite.

Chavez (50-2-1, 32 KOs) has won two fights in a row after a TKO loss to Andrzej Fonfara two years ago.
