While it is obvious that Christian McCaffrey will be the starting running back for the San Francisco 49ers so long as he is healthy, the competition for who will comprise the depth chart behind him just got much more interesting due to injuries.

Now, the door has been opened for undrafted prospect Corey Kiner.
