San Antonio Spurs head coach Gregg Popovich has missed his fourth consecutive game due to an undisclosed medical issue, leading to assistant coach Mitch Johnson stepping in as interim head coach. The Spurs secured a 118-105 victory over the Portland Trail Blazers, with Keldon Johnson and Malaki Branham each scoring 17 points. The team expressed uncertainty regarding Popovich's return, noting that he is 'doing good' but details about his condition remain scarce. Victor Wembanyama, a key player for the Spurs, mentioned that the team has not been in regular contact with Popovich but remains hopeful for his comeback. Meanwhile, the Spurs have faced challenges with injuries affecting their roster depth, but their bench contributed significantly to the win. Popovich, at 75, is the oldest coach in NBA history and has a record of 1,390 career victories.
