The 49ers can enter the playoffs anywhere from the No. 1 seed in the NFC to the No. 3 seed, depending on how they, the Vikings, and the Eagles do on Sunday.
The Vikings will end their season in Chicago against the Bears. Minnesota needs a win to stay alive for the No. 2 seed. The Eagles will kick off at the same time as the 49ers on Sunday afternoon against the Giants with the No. 1 seed in the balance.
Regardless of what happens in Chicago or Philadelphia, the 49ers can best set themselves up with a win over the Arizona Cardinals.
