Last week, rumors surfaced all over the place - claiming that Gennady 'GGG' Golovkin (36-0, 33KOs) was under the weather as his fight approached with IBF welterweight champion Kell Brook (36-1, 25KOs).

Even Brook's promoter, Eddie Hearn of Matchroom Sport, felt Golovkin was looking a little drained at the final press conference and the weighin. Usually a very talkative, friendly fighter - Golovkin bailed from both the final presser and the official weighin with doing almost no interviews.

Sick or not, Golovkin had enough in the tank to retain his middleweight belts by scoring a fifth round stoppage over Brook on Saturday night from the O2 Arena in London.

Tom Loeffler of K2 Promotions, who promotes Golovkin, denies the rumors and has no idea where they first began - but feels that it might be connected to Golovkin refusing to do interviews during fight week.

"I don't really know how those rumors came out. I think it was when the media wanted to do some interviews after the press conference and Gennady went back to the hotel. They thought he wasn't feeling well and it kind of snowballed from there," Loeffler said.

Abel Sanchez, who trains Golovkin, says his fighter was pissed off when he arrived to the weighin, because they were stuck in traffic for nearly two hours, so he just wanted to make weight and leave.

"On the weighin day, it took us an hour and forty minutes to get to the weighin from the hotel. It was stop and go, stop and go in city traffic. I think it pissed him off a little bit. He was just at the point now here he wants to fight. When you're trying to make weight and then you have that long ride, he just wanted to go back to the hotel and do his thing," Sanchez said.
