Chop Robinson is out of the concussion protocol. The Dolphins defensive end told reporters Thursday he cleared it, which puts him in line to play Sunday's home opener against Kansas City after sitting out Week 2 against San Francisco.
The timeline is the notable part. Robinson was diagnosed during a Wednesday practice before the 49ers game and went through all five steps of the protocol in a week, closing with a full-contact practice. Reports had him cleared as of Wednesday, with the player confirming it to reporters a day later. That last step is the one that matters for an edge rusher. The first four are symptom and exertion checks. Full contact is the only stage that approximates the job: helmet, hands, leverage, and the split-second collisions that a pass rusher can't avoid by running routes over the middle at half speed.
Miami's edge rotation spent one game without him and gets him back for the harder assignment. Kansas City stresses the edges on every early down, and a rotational end who can win a one-on-one without a blitz is the difference between rushing four and sending five. The 49ers week required a patch. This one doesn't.
What I'd watch is snap count, not availability. Clearing the protocol in seven days is the fast end of the range, and teams typically ease a player back rather than hand him his full workload in the first game after a head injury. If Robinson is on the field for his normal share Sunday, Miami's defensive front is at the depth it planned for in September.
My read: Robinson plays, and he plays more than a cameo. Miami didn't spend a week accelerating him through contact drills to park him on the sideline against the best quarterback on the schedule. If the Dolphins can generate pressure with four against Kansas City, that's the version of this defense that travels. If they can't, the protocol news won't matter much either way.
