Denver’s Mike Alvarado will fight Russian Ruslan Provodnikov in the first major boxing championship bout in Colorado in nearly 13 years, Alvarado’s promoter and manager confirmed Thursday.

The junior welterweight fight is scheduled for Oct. 19 at the FirstBank Center in Broomfield. It will air live on HBO immediately after a replay of the Juan Manuel Marquez vs. Tim Bradley fight from a week earlier.

Alvarado (34-1) is coming off a career-making victory by unanimous decision over Brandon Rios in March, a fight-of-the-year candidate. Provodnikov (22-2) lost to Bradley in a brawl two weeks before Alvarado-Rios.

“This matchup is perfect for Mike,” said Henry Delgado, Alvarado’s manager. “Mike can do what he wants. He can bang and he can box.”

Alvarado is expected to earn more than $1 million to fight Provodnikov, likely almost doubling his previous career high.

Provodnikov — who calls himself the “Siberian Rocky” — last fought Bradley at 147 pounds, the welterweight limit. But Provodnikov will come back down in weight to fight Alvarado at the junior welterweight limit of 140 pounds.

“When Mike reached this level, you fight the elite every time out,” said Carl Moretti, vice president of promoter Top Rank. “That’s what he’s doing. This is not a showcase fight. Mike proved his mettle. Provodnikov showed what he had against Bradley. It’s a big night for boxing.”

Colorado last hosted a major boxing title fight in September 2000, when Stevie Johnston failed to take the WBC lightweight belt from Jose Luis Castillo in a 12-round draw at the Pepsi Center.

“I was hoping for an easier showcase fight for Mike,” said Shann Vilhauer, Alvarado’s trainer. “Something like Stevie Johnston’s title defense at Magness Arena.”

Johnston defended his lightweight championship in March 2000 on the University of Denver campus in a fight that aired on ESPN.

“But this is HBO. They ain’t gonna put garbage on that network,” Vilhauer said.

Alvarado, in his victory over Rios in March, won the interim WBO junior welterweight title.

Details about ticket sales for the Oct. 19 fight will be announced later.
