With a couple of days to go before his second professional bout, Ryota Murata was still chilling. In fact, he looked so relaxed it was as if his fight was two months away.

"I don't turn my switch on until the day of the fight," Murata said at a Tokyo news conference on Wednesday.

Murata, the middleweight gold medalist at the 2012 London Olympics, will face Dave Peterson of the United States in the penultimate match of Friday's show held at sumo's mecca, Ryogoku Kokugikan.
