Dolphins could be without a key contributor against the 49ers in Week 2

Miami Dolphins pass rusher Chop Robinson entered concussion protocol leading into the squad's upcoming Week 2 matchup against the San Francisco 49ers. Robinson recorded a single tackle assist during Miami's 27-13 defeat against the Las Vegas Raiders to begin the season, though his head injury only emerged on the team's official participation updates later in the week.

After participating in a limited capacity during Wednesday's workout in Napa, California, the edge defender was downgraded to absent for Thursday's practice session.

Miami opted to remain on the West Coast rather than fly back home, giving coach Jeff Hafley extended time with the group ahead of Sunday. They face a 49ers squad that opened their campaign with a 27-7 victory against the Los Angeles Rams, though San Francisco also had an unnamed running back surface on their latest injury log before their home opener.
