Dylan Harper to Make Summer League Debut Saturday vs. Dallas Mavericks Despite Groin Injury

San Antonio Spurs guard Dylan Harper is expected to make his NBA Summer League debut Saturday against the Dallas Mavericks, sources told DallasHoopsJournal.com.

Harper, the No. 2 overall pick in the 2025 NBA Draft, sat out the Spurs’ appearances in the California Classic and their Las Vegas opener. The team has taken a cautious approach to his return, prioritizing long-term health. He has since been cleared to play and will be on a team-managed minutes restriction.

Saturday’s matchup at the Thomas & Mack Center is one of the most anticipated games of the Summer League, featuring a potential first showdown between Harper and top overall pick Cooper Flagg.

Flagg is coming off a gritty debut in the Mavericks’ 87–85 win over the Los Angeles Lakers. He finished with 10 points, six rebounds, four assists, three steals, and one block in 32 minutes. Though Flagg shot just 5-of-21 from the field and missed all five three-point attempts, his impact was felt late. In the final minute, he delivered a key block that led to Ryan Nembhard’s go-ahead three-pointer.

On Thursday, the Spurs opened their Las Vegas schedule with a 111–70 blowout win over the Philadelphia 76ers. David Jones-Garcia led the way with 24 points on 9-of-12 shooting, including 4-of-5 from three, adding five rebounds, three assists, and four steals. Riley Minix and Dexter Dennis each scored 14 points, while Kyle Mangas scored 11. Harrison Ingram contributed seven points, a game-high six rebounds, and four assists.

Tipoff between the Spurs and Mavericks is set for 3 p.m. CT on ESPN.
