McCaffrey's participation in this Sunday's service is still up in the air.

McCaffrey won't practise with the 49ers on Wednesday.

It's conceivable that the group is just giving him enough rest before of Sunday's contest with the Dolphins

Most fans aren't really surprised by this development given McCaffrey's history of ailments.

It would be a devastating blow to the 49ers' passing offence and rushing assault if McCaffrey was unable to play this coming Sunday.

Even with McCaffrey at their disposal, the 49ers will need Jordan Mason to put up a strong showing. Elijah Mitchell is already dead, after all.
