Spurs Rule Tobias Harris Out Against Thunder in Season Opener

San Antonio will begin its NBA season without veteran forward Tobias Harris, who remains sidelined by a left calf strain ahead of Tuesday night's home matchup against the Oklahoma City Thunder at the Frost Bank Center. Spurs coach Mitch Johnson ruled Harris out after Monday's practice, explaining that the offseason acquisition needs more on-court preparation before making his debut.

Harris sustained the injury during the first week of training camp and missed all five of San Antonio's preseason games. According to reports from NBC Sports and Hoops Rumors, the 34-year-old signed a two-year contract worth approximately $30.8 million in July after spending the previous two seasons with Detroit.

Johnson said the forward has made progress but still needs to work through the physical demands of returning to competition. The coach described the recovery as encouraging while emphasizing that Harris has not completed the necessary steps to return.

"He's ramping up, he's improving, he's progressing. But I would say he still needs some more progression on the court. You get on the court (coming off an injury) and there's quite a bit of layers you have to work through, whether that's how many people are on the floor (with you), the amount of contact, the amount of activity, distance, speed, etcetera.

So he's progressing well. We feel really good about it. He is ready to go and really wants to be out there, and I think he's right where he needs to be."

Johnson said after practice, according to ExpressNews.com.

Harris was expected to strengthen the Spurs' frontcourt alongside center Victor Wembanyama. His scoring ability across multiple areas of the floor could give San Antonio another offensive option, while his absence leaves the coaching staff with several alternatives at power forward.

Julian Champagnie and Harrison Barnes are among the players who could receive additional minutes, according to NBC Sports. Carter Bryant is another option, while San Antonio is also preparing to test a guard-heavy starting lineup.

According to Air Alamo, Johnson plans to start De'Aaron Fox, Stephon Castle, Dylan Harper, Devin Vassell and Wembanyama against Oklahoma City. The lineup combines three guards with Vassell and Wembanyama, presenting a different approach for the Spurs as they begin the season.

Harper, the second overall pick in the previous draft, is entering his second NBA season after spending his rookie campaign primarily in a reserve role. Hoops Rumors reported that he made 34.3% of his 2.6 three-point attempts per game last season before improving his preseason performance to eight makes on 14 attempts, or 57.1%.

"I've worked at it all summer, so there's no reason for me to be hesitant. No reason to pull back. Biggest thing is just taking the right shots at the right time," Harper said of his perimeter shooting, according to Hoops Rumors.

Oklahoma City, meanwhile, expects to have several important players available. Jalen Williams has recovered from the hamstring problem that restricted him during last season's Western Conference finals, while Ajay Mitchell is also ready after a calf injury forced him to miss the final four games of that series.

Center Chet Holmgren is available after missing all five preseason games with a quadriceps contusion. The Thunder's improved availability sets up a rematch between the teams that contested a seven-game Western Conference finals series, which San Antonio won.

Oklahoma City coach Mark Daigneault also praised Billy Donovan, who joined San Antonio as an assistant coach after 11 seasons as an NBA head coach and 21 years coaching college basketball. Donovan, a two-time national champion at Florida, was inducted into the Naismith Basketball Hall of Fame in September 2025 before taking the Spurs position in July 2026.

"There's a reason he's doing it. He loves to coach. He loves basketball.

He loves competing. He loves being around it," Daigneault said, according to ExpressNews.com. He previously worked under Donovan at Florida and in Oklahoma City.

Johnson said Donovan's extensive experience will help San Antonio manage its new lineup combinations and develop different ways to use its players. The Spurs are preparing to open their campaign against a Thunder team that is close to full strength.
