Former world champion Ricky Hatton died at the age of 46 on Sunday.
Nicknamed 'the Hitman', he won world titles at light-welterweight and welterweight and was one of Britain's most popular fighters.
His body was found at his home in Manchester on Sunday.
A Greater Manchester Police spokesperson said: "Officers were called by a member of the public to attend Bowlacre Road, Hyde, Tameside, at 6:45am today where they found the body of a 46-year-old man.
"There are not currently believed to be any suspicious circumstances."
Hatton, who won 45 of his 48 professional bouts across an esteemed 15-year career, last fought professionally in 2012.
He earned notable world title wins over Kostya Tszyu and Jose Luis Castillo, before defeats by Floyd Mayweather and Manny Pacquiao.
