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 being placed in the NFL's concussion protocol. Robinson's injury dates to around September 13th — approximately six days ago — and this update confirms he has not yet cleared protocol in time for this week's game.

Concussion return-to-play is entirely symptom- and protocol-dependent. The NFL's concussion protocol requires an independent neurologist to clear a player through a stepwise progression before he is eligible to return to play. No timeline estimate is possible from the outside — return is dictated by how Robinson's symptoms resolve and how he progresses through each protocol step, not by a calendar. The biology here is real: rushing a player back before full neurological clearance carries documented risk of repeat injury and prolonged recovery.

The key signal going forward is practice participation. Watch for Robinson to return to any practice activity — even limited — as the first indicator of protocol progression. Until then, his status should be treated as open-ended.
