Victor Wembanyama is the undisputed face of the Spurs, but San Antonio believes its success is the sum of the entire team. That idea is likely about to be tested.

Wembanyama exited Tuesday's Game 2 of the Spurs' first-round series against the Trail Blazers with a concussion, and San Antonio saw a 15-point lead with under eight minutes remaining slip away.

Had the Spurs won and taken a 2-0 series lead, there would be far less pressure on Wembanyama to return. Instead, San Antonio still needs to win three games to advance.

Here's a look at what Wembanyama's return timeline could look like under the NBA's concussion protocol.

Wembanyama's symptoms will dictate the total length of his recovery, but the Spurs star can't just expect to return the moment he feels good enough to play. The NBA has a strict concussion protocol with steps he must clear before he gets back on the court.

Wembanyama cannot fully participate in practice or play in a game for at least 48 hours after his diagnosis, though he can begin to resume activities as soon as 24 hors after his diagnosis. Once he does resume activities, Wembanyama must complete a series of steps without symptoms, including certain workouts and drills.

Only once every step has been completed and Wembanyama has been cleared by both a team doctor and the director of the NBA Concussion Program can he return to game action.

Wembanyama hit the court head-first in the first half of Tuesday's loss to the Trail Blazers. He entered concussion protocol and was quickly ruled out for the remainder of the game.

The NBA's concussion protocol prevents players from becoming full participants in practices or games for at least 48 hours after their diagnosis. Here is the league's wording:

"Prohibition from Full Participation. 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."

Here is the NBA's language regarding clearance to return to play:

"A player diagnosed with a concussion should be regularly monitored for 24 hours for the evolution of symptoms, and accordingly the player may not begin the return-to-participation exertion process until 24 hours after the time of injury. Initiation of the return-to-participation exertion process is determined by a team physician.

i. The return to participation process involves several steps of increasing exertion – from a stationary bike, to jogging, to agility work, to non-contact team drills.

ii. Each exertion stage must be directly monitored by a member of the team’s medical staff. With each step, a focused neurological examination is performed, and a player must be symptom free to move to the next step. If a player is not symptom free after a step, he stops until he is symptom free and begins again at the previous step of the process (i.e., the last step he passed without any symptoms).

iii. It's important to note that there is no timeframe to complete the process. Each injury and player is different and recovery time can vary in each case.

A player who had a concussion may not return to full participation without restrictions until:

i. He is without concussion-related symptoms at rest;
