“Rubio is a strong option for Gennady to fight,” Golovkin promoter Tom Loeffler of K2 Promotions told ESPN.com.
The 34-year-old Rubio (59-6-1, 51 KOs), who has triumphed in six consecutive bouts since losing a unanimous decision to Julio César Chávez, Jr., captured the interim WBC middleweight title by knocking out Domenico Spada on April 5.
Rubio is a hardened battler and the epitome of a professional.
Conversely, the 32-year-old Golovkin (30-0, 27 KOs) scored a third round TKO victory over Australian Daniel Geale to successfully defend the WBA and IBO middleweight belts in July at Madison Square Garden.
Golovkin floored the 33-year-old Geale (30-3, 16 KOs) in the second and then continued to mercilessly stalk the bleeding Aussie.
Sensing a beaten man, Golovkin exchanged punches with Geale in the third and landed a savage right hand that again sent the former two-time middleweight champion to the canvas.
Although Geale managed to regain his footing, referee Michael Ortega compassionately halted the bout at 2 minutes and 43 seconds of the decisive frame.
A bruising, ferocious and accurate slugger, Golovkin has never been toppled in over 375 contests.
Nicknamed “The Poison,” Rubio possesses cement hands that could endanger the “Good Boy.”
Unfortunately for the veteran Mexican veteran, GGG is a once-in-a-generation middleweight who won’t be stopped.
