Stephon Castle Injury Update: Spurs Guard Eases Ankle Concerns as NBA Finals Pressure Builds
Stephon Castle’s ankle scare could have been the kind of moment that reshaped an NBA Finals series. Instead, the San Antonio Spurs guard has given his team a much-needed dose of optimism at a tense point in their championship run.
Castle, one of the Spurs’ most important two-way players, tweaked his left ankle late in Game 2 of the 2026 NBA Finals against the New York Knicks. The injury came during a painful night for San Antonio, which lost 105-104 at Frost Bank Arena and fell behind 2-0 in the series after dropping both games on its home court.
But as the Finals shifted to Madison Square Garden, Castle delivered the update Spurs fans were waiting for: the ankle was responding better than expected.
“It’s been feeling good,” Castle said about his ankle via Tom Orsborn on X, formerly known as Twitter. “It feels a lot better than I thought it would initially. Obviously, I had some adrenaline running, kind of once I settled down, I started to feel it. Waking up the next day, actually felt really good.”
That statement did more than calm injury concerns. It preserved one of San Antonio’s most important strategic advantages: Castle’s ability to contribute offensively while serving as a primary defensive option against Knicks star Jalen Brunson.

How the Injury Happened
Castle’s injury occurred with 6:45 remaining in the fourth quarter of Game 2. As he attempted a jump shot, he landed awkwardly on Mikal Bridges’ foot and went down before limping to the Spurs’ bench.
For San Antonio, the timing was alarming. Castle had logged heavy postseason minutes and had become a central part of the Spurs’ Finals rotation. He remained on the bench for most of the closing stretch, which was unusual given his role, before returning to the floor for the final moments with 30.3 seconds left.
After the game, Spurs head coach Mitch Johnson offered a positive update.
“Right when he went out, I’m not sure, but when I checked on him with the training staff, he was available,” Johnson said of Castle.
Castle also downplayed the severity of the issue.
“I was all right,” Castle said, via Sam Owens of San Antonio Express-News.
“I think I kind of tweaked my ankle a little bit. But it started to feel good after I warmed it up,” added the 2024-25 NBA Rookie of the Year.
The early indication, then, was not that Castle had avoided discomfort entirely, but that the injury did not appear severe enough to remove him from the Finals picture.
Why Castle’s Availability Matters So Much
Castle’s health matters because his role has expanded beyond that of a young guard gaining playoff experience. He has become one of the Spurs’ most reliable postseason contributors.
During San Antonio’s run to its first NBA Finals appearance since 2014, Castle has averaged 18.8 points, 6.4 assists and 5.1 rebounds in the playoffs. Those numbers reflect his importance as both a scorer and a connector in the Spurs’ offense.
But his defensive responsibility may be just as important. Entering Game 3, Castle had been Brunson’s primary defender in the Finals, and Brunson had shot just 2-of-10, or 20.0%, when defended by Castle.
That matchup matters because Brunson is central to New York’s late-game offense. If Castle is limited laterally, unable to absorb contact, or hesitant changing direction, the Knicks can force switches and attack the weak spot. If Castle is close to full strength, the Spurs retain a defender who can pressure Brunson, contest pull-ups and help keep San Antonio’s defensive structure intact.
A Painful Game 2 Ending Added to the Drama
Castle’s ankle was not the only major storyline from Game 2. His late-game return also placed him in the middle of one of the contest’s defining plays.
With the score tied, Victor Wembanyama attempted to pass the ball to Castle, but Castle was not looking. The ball bounced off Castle’s back and into the hands of Jalen Brunson. Wembanyama then inadvertently fouled Brunson with 9.5 seconds remaining, and Brunson made the game-winning free throw in New York’s 105-104 victory.
Both Wembanyama and Castle acknowledged afterward that the moment came down to communication.
“That’s the most frustrating thing: to throw it away after putting in all this work,” Wembanyama said, via ESPN’s Michael C. Wright.
“I threw that one away. I messed up. It’s like the body reacts quicker than the mind. We needed to win that game. This game was ours. But at this point it’s done. Am I going to regret it? Yes, of course. Am I going to use that to fuel me and fuel us to the next game? Absolutely.”
Castle explained that he was trying to create space for Wembanyama rather than preparing to receive the pass.
“I didn’t see him throw it to me,” he said.
“I see Vic has the ball, tie game. I was just trying to give Vic space.”
The sequence became a brutal snapshot of San Antonio’s Game 2 frustration: an injury scare, a missed chance to tie the series, and a late miscommunication that helped the Knicks take control.
Signs From Practice Were Encouraging
The next major signal came before practice at Madison Square Garden. Castle said the ankle was “feeling good,” and during the portion of Sunday’s practice open to the media, he reportedly did not wear a brace and appeared to move well.
For a player dealing with a late-game ankle tweak, that detail matters. A brace is not always a sign of serious injury, and not wearing one does not guarantee a player is fully healthy. But combined with Castle’s own comments and Johnson’s postgame update, the overall picture was encouraging for San Antonio.
Castle’s availability was especially important because the Spurs entered Game 3 in a difficult historical position. They were trying to become the first team ever to lose the first two home games of the NBA Finals and still rally to win the championship. The 1993 Phoenix Suns and 1995 Orlando Magic had previously lost the first two Finals games at home and failed to win the title.
Castle Answers the Question on the Court
The strongest injury update eventually came through performance. Castle played in Game 3 and contributed meaningfully as the Spurs beat the Knicks 115-111 at Madison Square Garden, cutting the series deficit to 2-1. Victor Wembanyama led San Antonio with 32 points, while Castle added 23 points and sealed the victory with late free throws.
That outcome changed the tone around Castle’s ankle. Instead of becoming a limiting factor, the injury scare became part of a broader resilience story for San Antonio. Castle was not merely available; he remained effective in a high-pressure Finals environment.
Game 3 also reinforced why the Spurs needed him. Against a Knicks team built around Brunson’s shot creation and late-game scoring, Castle’s two-way presence gave San Antonio balance. His scoring helped relieve pressure from Wembanyama, while his defensive role remained central to the Spurs’ plan.
What It Means for the Spurs Going Forward
Castle’s ankle should still be monitored closely. Ankle tweaks can worsen if a player lands awkwardly again or compensates physically, especially in a Finals series where intensity, travel and short rest can magnify small injuries.
But the available evidence points toward a positive outlook. Castle said he felt better than expected, the Spurs’ staff considered him available after Game 2, he moved well in practice, and he played an important role in Game 3.
For San Antonio, that is a significant development. The Spurs are not deep enough into their Finals rotation to comfortably lose a guard who averages nearly 19 points per game in the playoffs and carries a major defensive assignment against Brunson.
Castle’s health also affects Wembanyama. The Spurs’ young franchise centerpiece needs reliable ballhandlers and decision-makers around him, especially in late-game situations. Castle’s ability to attack, pass, defend and absorb pressure gives San Antonio more structure around Wembanyama when the Knicks load up defensively.
The Bottom Line
The latest Stephon Castle injury update is encouraging for the Spurs. After tweaking his left ankle late in Game 2 against the Knicks, Castle said the ankle was feeling better than he initially expected. Head coach Mitch Johnson also indicated that Castle was available after being evaluated by the training staff.
Most importantly, Castle proved his readiness by playing a major role in San Antonio’s Game 3 win at Madison Square Garden. His 23-point performance and late free throws helped the Spurs cut the Finals deficit to 2-1, turning what began as an injury scare into a sign of toughness at the most important stage of the season.
For the Spurs, Castle’s ankle remains a storyline to watch. But for now, the update is clear: San Antonio’s young guard appears to have avoided a serious setback, and his presence could remain vital as the Finals continue.
