Former New York Knicks forward Anthony Mason is in critical condition after suffering a massive heart attack Wednesday, according to the New York Daily News.

Retired NBA analyst Peter Vecsey broke the news. He said Mason underwent several surgeries, with one lasting nine hours, and that he's fighting for his life.

He's probably best known for his rough play alongside fellow glass-pounders Patrick Ewing and Charles Oakley for five seasons with the Knicks during their '90s heyday — with one trip to the NBA Finals in 1994.

Mason was a key player for the Knicks, and it earned him the NBA's Sixth Man Award in 1995.

"In the early- to mid-'90s, he really epitomized the way those teams played because he was such a hard-nose player. ... He was a fan favorite, so people really gravitated toward him in the New York area," ESPN's Ian Begley said.

Mason excelled later in his career too. He was selected to the NBA All-Star game in 2001 while playing for the Miami Heat.

According to Sports Illustrated, Mason's two sons are also thriving in basketball — Anthony Jr. plays professionally in Europe, and Antoine plays guard at Auburn University.
