Charlie Sifford, the man who broke golf's color barrier, is in stable condition at South Pointe Hospital in Cleveland, Golf Channel has learned.
Sifford, 92, is battling a bacterial infection after also suffering a stroke.
Sifford was the first black golfer to receive a PGA Tour card after the PGA desegregated in 1961.
He won twice on Tour, taking the 1967 Greater Hartford Open and 1969 Los Angeles Open, before adding two more senior titles at the 1975 PGA Seniors' Championship and the 1980 Suntree Classic.
Sifford in 2001 became the first black golfer inducted into the World Golf Hall of Fame and last November became just the third golfer to receive the Presidential Medal of Freedom, the nation's highest civilian honor, joining Jack Nicklaus and Arnold Palmer.
Tiger Woods has oft cited Sifford as an inspiration, referring to him in a congratulatory tweet in November as "the grandpa I never had," adding, "Your past sacrifices allow me to play golf today. I'm so happy for you Charlie."
