The San Francisco 49ers have been bitten hard by the injury bug. However, it has mainly been in their running back room. Raheem Mostert is out for the year, and now the 49ers are also dealing with injuries to the remainder of their backs on the roster.

That is a massive headache, and Kyle Shanahan and the 49ers are bringing in a trio of veterans as they just try and get capable bodies to fill the void until the others are ready to roll.
