The Oklahoma City Thunder will open their 2026-27 regular season without three young players, while the San Antonio Spurs have ruled out veteran forward Tobias Harris for Tuesday night's Western Conference Finals rematch.

According to the NBA's latest injury report, Oklahoma City listed Otega Oweh, Thomas Sorber and Nikola Topic as out for its road matchup against San Antonio at Frost Bank Center.

Oweh remains sidelined following surgery to repair his right Achilles tendon, while Sorber continues recovering from right knee surgery. Topic is also unavailable after undergoing lower back surgery.

Meanwhile, Harris will miss his Spurs regular-season debut because of a left calf strain.

The 34-year-old forward joined San Antonio on a two-year, $31 million contract during the offseason after spending the previous two seasons with the Detroit Pistons.

Harris averaged 13.3 points, 5.1 rebounds and 2.5 assists across 63 games during the 2025-26 campaign, shooting 46.9% from the field and 36.8% from 3-point range.

Oweh's absence represents a significant setback for Oklahoma City's young backcourt.

The 23-year-old rookie suffered a ruptured right Achilles tendon during the preseason against the Indiana Pacers and subsequently underwent surgery. He is expected to miss the entire 2026-27 season.

A second-round selection in the 2026 NBA Draft, Oweh averaged 18.6 points, 4.8 rebounds, 2.7 assists and 1.8 steals during his final collegiate season at Kentucky.

Sorber, meanwhile, continues working toward his NBA debut after injuries disrupted his early professional career.

Topic also remains sidelined as he recovers from back surgery, further limiting Oklahoma City's available young talent.

Despite those absences, the Thunder enter Tuesday's matchup with their established core, led by Shai Gilgeous-Alexander, Jalen Williams and Chet Holmgren, available.

Oklahoma City will look to avenge last season's seven-game Western Conference Finals defeat against San Antonio, which advanced to the NBA Finals.

The Spurs will counter with Victor Wembanyama, De'Aaron Fox and Stephon Castle as they begin their pursuit of another championship appearance.
