LAS VEGAS – Canelo Alvarez and Amir Khan on Friday both weighed in at the catch weight of 155 pounds for Saturday’s pay-per-view fight at the new T-Mobile Arena.

The weigh-in took place before around 2,000 fans under ominous, dark clouds in Toshiba Plaza, in front of the the arena. It sprinkled a bit but Mother Nature largely cooperated with the promotion.

Alvarez (46-1-1, 32 knockouts) will be defending his RING and WBC middleweight titles for the first time. He won the titles by outointing Miguel Cotto last November. This is Alvarez’s fourth straight fight with a 155-pound catch weight, which is five pounds under the 160-pound limit.

Khan (31-3, 19 KOs) has never weighed in at more than 147 pounds for a fight. He is coming off a unanimous-decision victory over Chris Algieri in a welterweight fight in May of last year.

Weights for the other fights on the card Saturday are as follows:

Frankie Gomez (146 pounds) vs. Mauricio Herrera (145.5), welterweights; David Lemieux (160) vs. Glen Tapia (159.5), middleweights; Patrick Teixeira (159) vs. Curtis Stevens (160), middleweights; Diego De La Hoya (122) vs. Rocco Santomauro (122), junior featherweights; Jason Quigley (160) vs. James De La Rosa (162).
