The Miami Dolphins will be without defensive end Chop Robinson for Sunday’s meeting with the San Francisco 49ers. Robinson was diagnosed with a concussion at Wednesday’s practice and remains in concussion protocol, the team’s injury update said. He was limited on Wednesday before missing Thursday’s practice.
Miami has been practicing in Napa, California, after opening the season against the Raiders. Asked about the players who could take on Robinson’s pass-rushing responsibilities, coach Jeff Hafley pointed to Josh Uche, Clelin Ferrell, Rob Beal Jr. and Malik Herring. Hafley said the team could also use other approaches to help the group, and expressed confidence in the players’ preparation during the week.
Robinson, selected 21st overall in 2024, has recorded 10 sacks in his career and generated three pressures in Week 1, according to the source report. His absence removes one of Miami’s available edge rushers as the defense prepares to face quarterback Brock Purdy. The four players named by Hafley are expected to be among the options, although the coach did not lay out a specific rotation.
The Dolphins also ruled out inside linebacker Ronnie Harrison Jr., who has a hamstring injury. Long snapper Tucker Addington is listed as questionable with a shoulder issue after taking part in three straight limited practices. Those statuses leave Miami with another defensive absence and an unresolved special-teams availability decision before Sunday.
Robinson’s concussion history adds context to his current absence: he sustained two concussions in 2025, which kept him out for two games. The report does not provide a timetable for his return from the present protocol. For now, Miami’s stated plan is to distribute the work among its available defensive linemen and consider additional adjustments against San Francisco.
