In the span of a week, the San Francisco 49ers are watching their running backs drop like flies.
Superstar Christian McCaffrey was shut down for the season following a Week 13 snow game against the Buffalo Bills. He suffered a knee injury after missing the start of the season with Achilles tendinitis.
But the 49ers lost another running back following the game in Buffalo. Jordan Mason, who entered the year as the starter in place of McCaffrey, is now on injured reserve and likely to miss the remainder of the season.
