According to Golovkin's promoter, Tom Loeffler of K2 Promotions, the unified champion weighed in 165.1-pounds. For his part, Jacobs weighed in at 174.8-pounds. Both boxers were under the WBC's required 30-day maximum of 176-pounds.

Their fight will headline "Middleweight Madness" on March 18 at the legendary Madison Square Garden arena in New York City.

In the HBO Pay-Per-View co-feature, Roman "Chocolatito" Gonzalez will defend his WBC super flyweight title against Srisaket Sor Rungvisai. Both of them also took part in the WBC's 30-day weight check.

Gonzalez weighed in at 122.6-pounds, and Rungvisai weighed 125.9-pounds. Both boxers were under the WBC's maximum weight of 126.5-pounds.

Born and raised in Brownsville, a location  that has produced many legendary world champions, including Mike Tyson and Riddock Bowe, Jacobs has scored great KO'S against outstanding opponents during his nine years as a pro.

"Gennady is a great fighter, he always has several fight plans. They can plan what they want and overestimate me, but in the end I will be victorious on March 18," said Jacobs, from his training camp in Oakland, California.

In the most impressive fight of his career, on December 5, 2015, Jacobs dramatically defeated unbeaten former champion Peter Quillin in the first round in Brooklyn, New York.
