Chop Robinson Ruled Out vs. 49ers with Concussion

Dolphins edge rusher Chop Robinson has been ruled out for Sunday's game against the 49ers after entering the NFL's concussion protocol. The injury date has been resolved to September 13, 2026, meaning Robinson is approximately six days into the protocol as of this report.

Concussion is a neurological event — no return-to-play timeline can or should be generated from public information. What governs his return is the NFL's independent concussion protocol: Robinson must be symptom-free at rest, then pass stepwise exertional and functional stages, each cleared by an independent neurologist before he is eligible to return to game action. There is no fixed number of days or weeks attached to that process — it is entirely symptom- and protocol-dependent.

What we know is confirmed: Robinson is in protocol and confirmed out for Week 2. What happens from here depends on his clinical progression through those protocol steps, none of which is visible from the outside. The only honest watch signal is clearance language from the team — anything short of full protocol clearance is not a return signal.
