NEW YORK – Jermall Charlo has his own fight on which he is primarily focused this week.

In the back of his mind, however, the WBC world middleweight champion cannot wait to watch his twin brother, Jermell Charlo, get his opportunity to win back the WBC super welterweight title December 21. Nearly a year to the day that Tony Harrison upset him by unanimous decision, Jermell Charlo will get his rematch two weeks from Saturday night in Ontario, California.

Detroit’s Harrison, whose ankle injury postponed their rematch for six months, won’t have fought for just about a year by the time he encounters Charlo. Houston’s Jermell Charlo knocked out Mexican veteran Jorge Cota, Harrison’s replacement, in the third round of their June 23 bout at Mandalay Bay Events Center in Las Vegas.

The delay was frustrating for the former champion, but Jermall Charlo has noticed positive changes in his brother throughout this long wait for his shot at redemption.

“He’s hungrier now,” Jermall Charlo told BoxingScene.com. “With him taking a loss, you seen in the last fight he got the knockout and got [Cota] out of there. He’s where he wanna be. He’s gonna prevail. He’s gonna do great.”

Despite losing their first fight on all three scorecards last December 22 at Barclays Center in Brooklyn, handicappers have installed Jermell Charlo as more than a 2-1 favorite to beat Harrison in their 12-round rematch. FOX will televise this second battle between Charlo (32-1, 16 KOs) and Harrison (28-2, 21 KOs) as the main event of a tripleheader from Toyota Arena.

“I’ve seen the difference in how he carries himself and how he takes things more serious,” Jermall Charlo said regarding his brother. “He’s training harder. He’s becoming a complete Jermell Charlo now. With the loss, it makes you have to go get it back.”

Meanwhile, Jermall Charlo (29-0, 21 KOs) is set to defend his 160-pound crown against Ireland’s Dennis Hogan (28-2-1, 7 KOs) on Saturday night at Barclays Center. Showtime will air Charlo-Hogan as the main event of a tripleheader that’ll include England’s Chris Eubank Jr. (28-2, 21 KOs) and Russia’s Matt Korobov (28-2-1, 14 KOs) in a 12-round fight for the WBA’s interim middleweight title.
