Matt Rhule said it's a quad injury for Christian McCaffrey. Didn't know about it until after Saints' game. Wouldn't speculate on his status for this week.
Related players: Chuba Hubbard, D'Onta Foreman
Fantasy Impact:
McCaffrey did finish the game in Week 3 but given McCaffrey's recent past and injuries, owners may want to take note. For what it's worth, Person did tweet Hubbard said he thinks McCaffrey will be good to go and added Hubbard prepares to play every game. If he can't go, look for Hubbard and Foreman to see some kind of split in the workload.
