Former world heavy weight champion John Ruiz has quit after an 18-year pro career that ended in defeat to David Haye.
He bows out with a record of 44 wins (30KOs), nine losses, one draw and one no contest.
"I've had a great career but it's time for me to turn the page and start a new chapter of my life," said the 38-year-old American.
