The World Boxing Association, headed by Gilberto Mendoza, joins the mourning for the passing of former light heavyweight champion and Hall of Famer, Matthew Saad Muhammad.
Muhammad died on Sunday at age of 59, at Chestnut Hill Hospital in Philadelphia.
In addition to a Hall of Fame career and participation in many memorable fights, Saad Muhammad's story was inspiring.
Abandoned as a child, he grew up to fame and became a light heavyweight world champion against all odds.
In 1979, Saad Muhammad, known for his punching power and heart, knocked out Marvin Johnson in a rematch to win the light heavyweight title in Indianapolis, Johnson 's hometown.
He grew up with the nuns of Catholic Social Services and in reformatories, until he met boxing. He discovered the sport to see Muhammad Ali in Philadelphia.
It became a real figure of semi heavyweights . He retired in 1992 with 49-16-3 , 35 KO 's.
Rest in Peace!
