San Antonio Spurs head coach Gregg Popovich will miss at least two games as he recovers from an undisclosed illness. Assistant coach Mitch Johnson will serve as interim coach, leading the team during his absence. Popovich, the NBA's all-time winningest coach, has faced health issues before, and his absence is a reminder of the unpredictable nature of coaching in the league. The Spurs won their last game under Johnson's guidance and will look to maintain their performance as they face upcoming opponents.
