McCaffrey sidelined Wednesday

49ers RB Christian McCaffrey (knee) won't practice on Wednesday, HC Kyle Shanahan said. Shanny added that McCaffrey "just felt something" in that left knee during last week's game and that they're "hopeful" he'll be able to play vs. the Dolphins on Sunday. That's not quite as reassuring as the reports on CMC's status over the previous couple of days. We're still tentatively expecting him to play this weekend, but we'll continue to keep a close eye on that knee.
