Robinson Officially Being Out Highlights Final Dolphins Injury Report of Week 2

In this story:
The expected news involving Miami Dolphins edge defender Chop Robinson came before practice Friday when head coach Jeff Hafley ruled out him of the team's Week 2 game because of a concussion.
Additionally, Hafley confirmed that Robinson is in the concussion protocol and was injured during practice Wednesday. Hafley said Robinson was doing well, but didn't provide additional details.
Robinson was one of two players the Dolphins ruled out Friday, the other being veteran linebacker Ronnie Harrison Jr.
The Dolphins had one player listed as questionable, that being long-snapper Tucker Addington, who sustained a shoulder injury while making a tackle during the 27-13 loss against the Las Vegas Raiders last Sunday.
Robinson and Harrison didn't practice Friday, while Addington and tight end Seydou Traore (Achilles/thumb) were limited. Traore, though, didn't get a game status designation.
QB Malik Willis (toe) and safety Dante Trader Jr. (hamstring) also didn't get a game status despite being on the injury report all week. Both were full participants Friday.
THE ROBINSON RAMIFICATIONS
Beyond the potential long-term implications of Robinson's third concussion in 10 months, the Dolphins are looking at a significant loss for their defense ahead of a matchup that is not favorable in the first place.
While his performance in the season opener was pretty underwhelming, Robinson still remains the team's best pass rusher, if not they're only threat in that department.
The stat sheet showed Robinson with only one assisted tackle against the Raiders in Week 1, but he did have two of the team's four quarterback pressures, according to Pro Football Reference.
If Robinson can't play, the Dolphins would be down to three edge defenders on their active roster — Josh Uche, Robert Beal Jr. and Malik Herring — and it's almost certain one would be elevated from the practice squad.
Even for the Las Vegas game, the Dolphins elevated former fourth overall pick Clelin Ferrell to help out on the edge, so he likely would be first in line to get the call, which would set him up for a second consecutive reunion game against the team that drafted him (Raiders) and the team for which he played last season (49ers).
The Dolphins do have three other edge defenders on the practice squad with rookie seventh-round pick Max Llewellyn, Rodney McGraw and Amari Gainer, so maybe the Dolphins would prefer giving Llewellyn a taste of NFL experience — especially considering Ferrell wasn't noticeable in his limited defensive snaps against the Raiders.
Harrison played only special teams against the Las Vegas Raiders in the season opener, and it's not like the special teams performed well in that game, so his absence wouldn't be nearly as significant.
The Dolphins likely will use their second practice squad elevation on long-snapper Cal Adomitis if there's any question about Addington's ability to perform his duties after being injured while making a tackle on a punt return against the Raiders.
THE 49ERS PICTURE
The 49ers, meanwhile, ruled out one player Friday, rookie wide receiver De'Zhaun Stribling. He underwent surgery Friday for an ankle injury he sustained in the 27-7 victory against the Los Angeles Rams in Australia and is expected to go on injured reserve.
Rookie running back Kaelon Black also didn't practice Friday because of the groin injury he sustained during the week, but he was not ruled out for the game, but rather questionable.
Black had a strong NFL debut against the Los Angeles Rams in Australia in Week 1 and his bruising style gave the 49ers running game a second option behind star Christian McCaffrey.
Also listed as questionable was veteran kicker Eddy Pineiro, who didn't practice all week because of illness.
The 49ers do not have a kicker on the practice squad, so they would have to sign a replacement Saturday to kick the very next day if Pineiro turned out to be too sick to kick against the Dolphins.
