Don Cronson's, Mason's agent when he played in the NBA, told the Times he spoke to a member of Mason's immediate family on Thursday morning.
“Right now, it’s day to day, but that’s an improvement from moment to moment,” Cronson told the Times. Cronson also said Mason might need a heart transplant if he survives.
Mason, 48, was at a hospital for a checkup on heart issues when he suffered the heart attack.
A 13-season NBA veteran, Mason spent five with the Knicks from 1991-96. He was part of the 1994 Knicks team that reached the NBA Finals, and is perhaps most renowned for his toughness and ability to matchup with players who were even bigger than his 6'7" frame.
Mason also spent time with the New Jersey Nets, Denver Nuggets, Charlotte Hornets, Miami Heat and Milwaukee Bucks. He was named an All-Star in 2001, Sixth Man of the Year in 1995 and All-NBA Third Team and All-Defensive Second Team selections in 1997.
Retired NBA writer Peter Vecsey first reported on Tuesday that, at that time, Mason had underwent four surgeries after suffering the heart attack and congestive heart failure.
