Tom Loeffler of K2 Promotions says that WBA middleweight titlist Gennady Golovkin will be back on HBO in November, his third and final appearance on the network in 2013, but he may fight again in August or September if they can find the right opportunity.

Golovkin (27-0, 24 KO) has intended to fight five times this year, and he's already gone to the ring on three occasions. He beat Gabriel Rosado on HBO in January, and returned this past Saturday to knock out Matthew Macklin in three rounds. Between those fights, and off HBO, he defeated Nobuhiro Ishida in Monte Carlo.

The 31-year-old titleholder is crushing foes left and right, and may have a difficult time securing a notable opponent for November. Sergio Martinez won't fight until 2014 and will be kept away from Golovkin when he does return (at least at first), Julio Cesar Chavez Jr is fighting on September 7, and Peter Quillin is with Showtime due to his status as a Golden Boy/Al Haymon fighter. It's possible that Martin Murray could take a crack at Golovkin following his somewhat controversial loss to Martinez in April, but that would require his obtaining a visa to fight in the United States most likely, and he's had issues with that before due to time spent in prison in his younger days.

The most interesting possibility -- at least at middleweight -- may be the winner of the August 17 fight between IBF titlist Daniel Geale and Darren Barker. Those two will be broadcast on HBO. Both would have opportunities at home in Australia and the UK respectively, though, so a hard-line stance by HBO, for instance, may not be effective there.
