The 49ers have ruled CB Emmanuel Moseley (concussion), CB Dontae Johnson (groin) and CB K'Waun Williams (knee, hip) out for Sunday's game against the Dolphins. CB Ahkello Witherspoon (hamstring) is also questionable. He missed last week's game against the Eagles but managed limited workouts this week. We'll check on Witherspoon's status Sunday, though he's not much of an IDP factor either way. The big takeaway here is that the Niners will miss at least 4 of their top 6 corners -- with Richard Sherman still on IR. That can only help Miami QB Ryan Fitzpatrick, WR DeVante Parker and TE Mike Gesicki.

The 49ers have ruled CB Emmanuel Moseley out for Sunday night's game against the Eagles with a concussion. The team has also ruled CB Ahkello Witherspoon out (hamstring) and deemed slot CB K'Waun Williams questionable. With Richard Sherman already out, San Francisco will be missing at least 3 of its top 4 corners for the game. The question, of course, is whether the banged-up Philly offense can exploit that weakness.
