TORRANCE, Calif. (Reuters) - Boxing great Floyd Mayweather said his time in the ring is finished and that he is focused on other projects including his fast-growing chain of boxing fitness gyms and his high-profile promotion company.
The 42-year-old American, who has retired in the past only to be drawn back for another colossal payday, said he is content to hang up his gloves with an unblemished 50-0 record.
"I've got calls to get back into the ring, but my health is my wealth," Mayweather told Reuters at the recent opening of a Mayweather Boxing + Fitness gym in Torrance, California.
"Boxing is a very, very brutal sport. In the last few years a lot of fighters have died inside that squared circle."
American Patrick Day died in October as a result of a traumatic brain injury he suffered when he was knocked out and two professional fighters perished within a week's time in July from damage sustained during their bouts.
"You have got to know when to hang it up. I had a great career," he said, throwing cold water on the prospects of a rumored rematch against Manny Pacquiao or Canelo Alvarez next year.
Mayweather, who won the first of his 12 world titles in 1998, first announced his retirement in 2007 but quickly returned to the ring.
