Dolphins’ Chop Robinson Misses Practice With Concussion

Miami Dolphins edge rusher Chop Robinson did not practice Thursday after being limited Wednesday while in the concussion protocol, making him highly unlikely to play Sunday against the San Francisco 49ers. The timing of the concussion remains unclear, as he was not known to show symptoms during Miami’s Week 1 loss to the Raiders and could have developed them afterward or during practice. Robinson’s absence would be a significant blow to a Dolphins defense that struggled to pressure the quarterback in Week 1, with Malik Herring and Robert Beal among the candidates to replace him and a practice-squad elevation possible. Linebacker Ronnie Harrison Jr. also missed practice with a hamstring injury, while several other Miami players were limited or practiced fully.
