The NBA released the following statement on Stern's health status:
NBA Commissioner Emeritus David Stern remains in serious condition following emergency surgery to address a sudden brain hemorrhage on Thursday. He is receiving great care and surrounded by his loved ones. The Stern family and everyone at the NBA appreciate the incredible outpouring of support. Our thoughts and prayers remain with David and his family.
Serious condition means vital signs "may be unstable and not within normal limits," according to American Hospital Association guidelines, and a patient is "acutely ill" with questionable indicators. This is different from critical condition, which indicates a patient "may be unconscious" with unfavorable indicators.
From 1984 to 2014, Stern oversaw the incredible financial growth of the NBA and helped turn basketball into a global sport as the league's longest-serving commissioner.
He handed off the job to Adam Silver on Feb. 1, 2014, and was inducted into the Naismith Memorial Basketball Hall of Fame later that year.
