CMC "day to day," will be managed

49ers HC Kyle Shanahan on Monday labeled RB Christian McCaffrey "day to day" with "knee irritation" and said that CMC will be managed during the week. It's unclear if McCaffrey's snaps and touches will need to be "managed" on game day. His 63% snap rate in Sunday's win over the Saints was his lowest since his 49ers debut in Week 7. And after tallying 27 and 20 opportunities (carries + targets) in Weeks 8 and 10, McCaffrey has gone for 14 and 17 the past 2 games. We'll keep a close eye on this knee situation going forward.
