🏀 Victor Wembanyama Injury Update: How Long is Wemby Out, When Will He Return to Spurs?

Victor Wembanyama has been diagnosed with a concussion after landing hard in the second quarter of the San Antonio Spurs' Game 2 loss to the Trail Blazers on Tuesday night. He was ruled out for the rest of the game, and the Defensive Player of the Year and MVP finalist could be in jeopardy of missing more time in the 2026 NBA playoffs.

Below, I break down what happened to Wembanyama in Game 2, how long he's expected to be out, how the NBA's concussion protocol works, and how his injury could impact the Spurs vs. Blazers odds entering Game 3 in Portland on Friday (10:30 p.m. ET, Prime Video).

🏥 What happened to Wembanyama in Game 2?

After a record-setting postseason debut in Game 1, Wembanyama was having a major impact in Game 2 with five points, four rebounds, an assist, a block, and countless deterred shots at the rim as he helped the Spurs stay within striking distance early on.

Then, with 8:57 left in the second quarter and his team down by two points, Wembanyama lost his balance while driving on Portland's Jrue Holiday and fell face-first onto the floor. He stumbled when he initially tried to get up before sitting for 30 seconds before leaving the court under his own power and sprinting straight to the locker room.

The Spurs announced shortly after that he had entered the NBA's concussion protocol and was ruled out for the rest of the game. The team announced after the game that he had been diagnosed with a concussion, and ESPN's Shams Charania reported that he'll undergo further testing on Wednesday ahead of Game 3 on Friday.

With Wemby on the bench, the Trail Blazers outscored the Spurs by one point across the final 33 minutes in a 106-103 win to even the series at 1-1.

⏳ How long will Wemby be out?

We still don't know the exact timeline for Wembanyama's recovery after he was diagnosed with a concussion on Tuesday - and per the league's own policy, there can't be one just yet. The NBA's concussion protocol is explicit that recovery timelines are a case-by-case basis and aren't determined until the player passes protocol.

Spurs head coach Mitch Johnson confirmed to reporters that Wembanyama entered the concussion protocol on Tuesday, so he could be eligible to return within 48 hours. San Antonio doesn't play until Friday, which would be 72 hours after Wemby's injury.

While Wembanyama can technically return for Game 3, recent history suggests that's unlikely. Here are a few recent examples of NBA players entering the concussion protocol for better context on how long Wembanyama will be out:

• Tyrese Maxey (March 2024): Maxey was diagnosed with a "delayed and mild" concussion two days after hitting his head on another player's knee. The 76ers star missed four games (9 days) before clearing protocol.
• Lonnie Walker (March 2025): Walker hit the back of his head on the floor and was ruled out for the rest of the game. The 76ers guard missed four games (9 days) before returning, but then missed the next three games (8 days) with headaches.
• Jalen Smith (January 2026): Smith entered the concussion protocol after a head-to-head collision with LaMelo Ball. The Bulls forward missed 2 games (7 days) before returning to action.

According to a Hashtag Basketball study of 15 years of concussion data with 130 reported concussions, the average time missed for a concussion is six days. If that holds in this case, Wembanyama would miss Game 3 (Friday) and Game 4 (Sunday) with a chance to return for Game 5 in San Antonio next Tuesday.

🏀 How does the NBA's concussion protocol work?

The NBA's concussion protocol isn't a fixed timeline for return when a player sustains a concussion. Rather, it's a framework for screen and return-to-play guidelines before a player is eligible to return to the court.

According to the league's 2025-26 Concussion Policy Summary, if a player is diagnosed with a concussion, "he cannot return to full participation without restrictions: (i) for at least 48 hours after the time of injury; and (ii) until after he completes the required return-to-participation process."

That return-to-participation process requires a player to fulfill each stage without any symptoms before moving to the next stage:

• Stationary bike
• Jogging
• Agility work
• Non-contact team drills

A team physician initiates the process, and a focused neurological examination is performed at each stage. If symptoms return at any point, the player has to stop and restart at the previous symptom-free step. The final return-to-play decision is made by the team physician after consultation with the director of the NBA Concussion Program.

The league's policy is explicit that there is no fixed timeline for clearance and that recovery varies in each case. That means we likely won't know when Wembanyama will return until he is on the verge of his return.

📊 How Wemby injury affects Spurs vs. Trail Blazers odds

San Antonio came into Game 2 as -2500 series favorites with Portland trading at +1200 to win the series after the Spurs' 13-point win in Game 1. They entered Game 2 favored by 11.5 points before losing Wemby in the second quarter and ultimately losing the game, tying the series at 1-1 ahead of Game 3 in Portland.

The Spurs are now favored with -550 odds (bet $55 to win $10) to win the series at FanDuel with the Blazers priced at +410 (bet $10 to win $41). San Antonio is a 1.5-point favorite to win Game 3 on the road - a line that is clearly baking in the expected loss of Wembanyama for the narrow road favorite - and its NBA Finals odds jumped to +650.

It's impossible to fully quantify Wemby's impact on the court: he was the best defender in the NBA this year with the highest block rate (9.4%) and defensive rebound rate (33.9%), but he also ranked third in PER (29.9) and fourth in points per 36 minutes (30.9). The Spurs will turn to center Luke Kornet and forward Carter Bryant to fill Wemby's minutes should he miss time in this series.
