Ricky Hatton's family has paid tribute to the former world champion, who was found dead at the age of 46 at his home in Manchester on Sunday.
"He had a heart as big as his smile, and his kindness, humour and loyalty touched everyone who was lucky enough to know him," the Hatton family said.
"As a family, our loss is immeasurable, and words cannot truly capture the pain we feel. Yet in the midst of our grief, we have been deeply moved by the overwhelming outpouring of love and support.
"Richard's memory will forever remain in our hearts, in the hearts of his fans, and in the sport he loved so dearly."
A Greater Manchester Police spokesperson said "there are not currently believed to be any suspicious circumstances" surrounding Hatton's death.
