LAS VEGAS – Canelo Alvarez and Daniel Jacobs made weight Friday afternoon at T-Mobile Arena.

During their face to face, they were butting heads and had to be pulled apart after Canelo pushed Jacobs and the two were trying to get to each other as their teams were holding them back.

Only 17 hours until they have to get on the scale again.

Now that the middleweight champions have met their contractual obligations by weighing in at or below the division’s limit, they’re concentrating on rehydrating within what’s allowable. Neither Alvarez nor Jacobs can weigh more than 170 pounds at a second-day weigh-in Saturday morning.

Representatives for Alvarez insisted on the rehydration clause because so much was made of how much weight Jacobs gained following a weigh-in for his middleweight title fight against Gennadiy Golovkin in March 2017 at Madison Square Garden in New York. Jacobs skipped the IBF’s second-day weigh-in the morning of the Golovkin fight.

Golovkin’s team took issue with Jacobs skipping that second-day weigh-in because Golovkin and his handlers were under the impression Jacobs would weigh in again.

Jacobs since has won the IBF middleweight title, but the IBF’s second-day weigh-in rule isn’t in effect because this is a middleweight title unification fight. Jacobs fought Golovkin only for Golovkin’s WBA and WBC middleweight titles.

Alvarez edged Golovkin by majority decision in their 12-rounder September 15 at T-Mobile Arena to take the WBA and WBC 160-pound championships.

The 28-year-old Alvarez, of Guadalajara, Mexico, stepped on the Nevada State Athletic Commission’s scale at 159½ pounds. The 32-year-old Jacobs, of Brooklyn, New York, officially weighed exactly 160 pounds.

The 5-feet-8 Alvarez (51-1-2, 35 KOs) is listed as a 4-1 favorite over the 6-feet Jacobs (35-2, 29 KOs) at the MGM Grand sports book. DAZN will stream Alvarez-Jacobs as the main event of an eight-bout card (7:30 p.m. ET/4:30 p.m. PT).
