San Diego, Arizona and Minnesota clinched division titles Sunday, while Philadelphia surged into the playoffs as at least a wild card.
The Chargers (11-3) edged Cincinnati 27-24 and when Denver lost to Oakland, the AFC West belonged to San Diego for the fourth straight season.
Green Bay's 37-36 defeat at Pittsburgh gave the Vikings (11-2 and playing at Carolina on Sunday night) the NFC North.
The Cardinals (9-5) won the NFC West for the second successive year by beating Detroit 31-24, then seeing San Francisco lose at Philadelphia 27-13. The Eagles (10-4) moved into the postseason with that win.
