San Antonio Spurs rookie Dylan Harper had surgery to repair a partial tear in his left thumb after suffering the injury during a workout in San Antonio.

The San Antonio Spurs announced Friday that rookie guard Dylan Harper underwent successful surgery to repair a partial tear of the collateral ligament in his left thumb.

The team said Harper sustained the injury Wednesday in San Antonio during an offseason workout. No specific timetable was provided for his recovery, and the Spurs noted they will provide updates as appropriate.

Harper, the No. 2 overall pick in the 2025 NBA Draft, entered the summer as one of the most anticipated rookies in the league after a standout season at Rutgers. The 6-foot-6 guard was drafted to join Victor Wembanyama as a centerpiece of San Antonio’s rebuild, with expectations that he will contribute immediately in his first professional season.

The injury adds another obstacle to what has already been an abbreviated summer for Harper. He missed the California Classic and the Spurs’ first Summer League game in Las Vegas due to groin soreness before appearing in two contests. In those outings, Harper averaged 16 points, four rebounds, two assists and one steal while shooting 35.7% from the field.

His debut against Dallas featured 16 points, six rebounds, and two assists in 20 minutes, showing flashes of the scoring and physicality that made him a top prospect. He followed with another 16-point performance against Utah, adding two rebounds and two assists.

Over his two games, Harper committed seven turnovers and struggled from three-point range, but the Spurs pointed to his aggressiveness and ability to attack defenses as encouraging signs.

The Spurs drafted Harper with the vision of pairing him with Wembanyama to form a young core capable of returning the franchise to contention. While his recovery from thumb surgery will be closely monitored, the organization has emphasized patience with its long-term outlook. Harper is expected to play a key role when San Antonio begins its season.
