The New England Patriots have their focus on Week 2, but they'll have one less thing to worry about when Week 4 arrives.
Christian McCaffrey missed the 49ers' season-opener against the New York Jets due to a calf and Achilles injury. San Francisco ruled out the star running back for this Sunday, and Kyle Shanahan admitted the team mulled the idea of putting him on injured reserve.
That was made official Saturday, according to ESPN's Adam Schefter. The 28-year-old will miss the next four games before the Niners decide mid-October what to do with him.
