Gennady Golovkin has spoken out about Canelo Alvarez’s failed drugs test.

The middleweights are slated to appear in a rematch of their split-decision fight from last year.

Alvarez recently tested positive for clenbuterol, a banned substance. The Mexican blamed it on tainted meat, a problem supposedly affecting a number of Mexican athletes.

Speaking to Ring Magazine however, Golovkin said:

I don’t want to talk about it much because if it’s positive that it’s a performance-enhancing drug for him, that’s just outrageous.

But my hope is that all parties involved will cooperate in the investigation and make more efforts to ensure clean boxing. That’s what I’m for, clean boxing.

The world champion Golovkin will step into the T-Mobile Arena in Las Vegas to put his WBA, WBC, and IBF titles on the line, and so his trepidation may be understandable surrounding a failed drugs test for his opponent.

The 35-year-old Kazakhstan-native went on to say:

I am an athlete who respects the sport and this surprises me and bothers me because it had never happened to me.

I will submit to all the tests that require me to clarify this embarrassing situation and I trust that at the end the truth will prevail.
