San Antonio Spurs coach Gregg Popovich, 76, was hospitalized following a medical incident but has since returned home and is reporting good health. The winningest coach in NBA history experienced a mild stroke in November and has confirmed he will not return to coaching this season. Popovich, who has been with the Spurs for 29 years, has guided the team to five NBA championships and Olympic gold. His focus now is on recovery, with hopes of returning to coaching in the future. Spurs assistant Mitch Johnson has taken over as interim head coach during this time.
