Over the past decade, the NFL has moved from vague injury handling to a formal Concussion Protocol with independent spotters, removal triggers, and a structured five-step return-to-play system. Players now recognize symptoms like dizziness or fogginess as serious, marking a shift from the old “shake it off” mentality.

In 2025, the NFL banned teams from supplying smelling salts during games—a change aimed at clearer sideline diagnostics. Smelling salts can mask concussion symptoms, making it harder to evaluate players accurately. While players can still bring their own, this move reduces team influence and prioritizes honest assessments.

This ban joins other safety reforms: the hip-drop tackle was outlawed, the kickoff was redesigned to lower impact risk, and Guardian caps were made more common. Combined, these efforts reduce both concussive and sub-concussive hits while preserving gameplay.

Are they working? Concussion numbers rose in recent years, likely due to better detection. Yet targeted rule changes—like those in 2018—led to measurable decreases. The protocol ensures players don’t return prematurely, protecting both health and game integrity.

Will it end CTE? No—not yet. CTE stems from repeated head trauma and remains hard to detect early. But limiting head impacts and ensuring fast, accurate diagnoses are crucial steps. The smelling salts ban may seem minor, but it’s part of a bigger mission: making football safer without stripping its essence.
