It’s a familiar matchup for the 49ers as they take on the Arizona Cardinals just 17 days after their win in Arizona. The 49ers escaped Arizona on Halloween with a 28-25 victory that saw Jimmy Garoppolo carry the offense with four touchdown passes, and a defense that barely held on long enough to get the job done. The two division rivals will close out their season series Sunday at Levi’s Stadium.

Here are the three matchups that could decide whether the 49ers sweep or Arizona can earn a split:

Deebo Samuel vs. Patrick Peterson

With George Kittle out and Emmanuel Sanders questionable for Sunday, Samuel could be the best receiver on the field for the 49ers. With that comes a matchup against one of the better cornerbacks in league. Samuel had the best game of his career against Seattle with eight receptions for 112 despite having a couple of drops that could have added to his numbers. If Sanders can’t go, expect Jimmy Garoppolo to target Samuel a bit but with that comes throwing at Peterson, a three-time All-Pro corner.
