Palmer (knee) didn't practice Friday and is listed as questionable for Sunday's game against the Panthers.
Palmer downgraded to no participation Friday after two limited practices to begin the week, so he may be trending in the wrong direction. If Palmer joins DJ Chark (hip) on the sideline Sunday, Quentin Johnston and Ladd McConkey would be joined by Derius Davis, Simi Fehoko or Brenden Rice in three-receiver sets.
