George Groves is preparing for his WBC super-middleweight world title showdown with Badou Jack alongside knockout specialist Gennady Golovkin, according to the unbeaten Kazakh's trainer.

Mandatory challenger Groves was due to fight Jack for the WBC strap on August 22, before the bout was postponed without explanation. However, there are rumours the pair could meet on the undercard of Floyd Mayweather's next fight on September 12.

Groves is currently training at undefeated WBA middleweight champion Golovkin's Summit Gym in Big Bear, California. After seeing Groves in action, Golovkin's trainer Abel Sanchez admitted he can only see the Londoner's fight going one way.

"He'll stop Badou Jack," Sanchez told Sky Sports. "I don't think Jack understands the level that George is at.

"Just by fighting Carl Froch and having been in that situation makes a big difference mentally. Physically, he's such a strong, rugged guy that Badou won't be able to handle him.

"Once I get back, there's several guys in my gym that George will be sparring with.

"George likes [training in Big Bear], and [his trainer] Paddy Fitzpatrick likes it too. The altitude helps him but he's getting away from distraction to an area where he can concentrate on what he's doing, and prepare the way it's supposed to be for a big fight."

Golovkin next faces David Lemieux in a middleweight title unification bout in New York on October 17. However, Sanchez does not believe Groves and Golovkin will get a chance to spar together.

"I only like Golovkin in camp for eight to nine weeks," Sanchez added.

"Our fight is on October 17 so he won't be back until August 17. By that time, George will be finishing up and Golovkin is just starting - so probably not."
