Tom Loeffler of K2 Promotions believes that former two time world title challenger Marco Antoknio Rubio will be a tough test for his fighter WBA middleweight champion Gennady Golovkin (30-0, 27 KOs) in their West Coast fight on October 18th at the StubHub Center in Carson, California.
The 34-year-old Rubio has twice fought for world titles and twice gone down to defeat to Kelly Pavlik and Julio Cesar Chavez Jr. Rubio has tried and failed in getting exposed by those two fighters.
2012 super heavyweight gold medalist Anthony Joshua is in Austria sparring with IBF/IBO/WBA/WBO heavyweight champion Wladimir Klitschko (62-3, 52 KOs) to get him ready for his fight next month against unbeaten #1 IBF Kubrat Pulev (20-0, 11 KOs) at the O2 World Arena in Hamburg, Germany.
