Miami Dolphins edge defender Chop Robinson is ruled out for Sunday’s game against the San Francisco 49ers due to a concussion. Dolphins coach Jeff Hafley says Robinson will not play in the 4:25 p.m. ET kickoff at Levi’s Stadium.

Hafley reports Robinson sustained the concussion during Wednesday’s practice. Multiple outlets frame the decision as a week-to-week availability call ahead of the Dolphins’ Week 2 matchup in San Francisco. While one report focuses on the specific timeline leading to the ruling out (injury during practice, coaching comments before Friday practice), the other outlet reiterates that he is unavailable for the game because of the concussion, without adding additional details.

No sources provided here indicate a return date or further medical information beyond the concussion diagnosis and the immediate impact on Sunday’s lineup.
