Alvin Kamara suffered a concussion on the first series in Thursday's game against the Falcons, and will not return.
Kamara took a helmet-to-helmet shot mere moments into the game, but the Saints waited until there was 14 seconds remaining in the first half to declare him done for the night. It's a crushing, crushing blow for fantasy owners in the first week of the playoffs. If there's any good news, it's that Kamara now has 10 days to get cleared for Week 15. His early departure snaps a streak of five straight games with at least 116 yards from scrimmage.
