The Saints on Saturday promoted RB David Johnson from the practice squad to the active roster. That likely means there will be a role for him Sunday against the Rams. We wouldn't bet on a lot of usage, though. Dwayne Washington and Jordan Howard combined for just 7 snaps last week, with Howard drawing the only carry between them.

Saints RB Mark Ingram is expected to miss 3-4 weeks with an MCL sprain suffered in Sunday's win over the Raiders, per NFL Network's Ian Rapoport. Ingram's absence leaves Dwayne Washington as New Orleans' #2 RB -- and should mean even more work for RB Alvin Kamara.

Saints RB Alvin Kamara (ribs) is officially inactive for today's game vs. the Vikings. It's a surprise after he played through this issue last week. Insider Nick Underhill says that Kamara is "looking to get healthy for the long haul." When Kamara missed Week 2, Ingram handled 10 of 16 RB carries and saw 2 targets. He wasn't at 100% for that game, though, and could see a bit more work today. RB Tony Jones is a healthy scratch today, so it's Ingram, Dwayne Washington and Latavius Murray, just called up from the practice squad, in New Orleans' backfield.
