Prediction and betting odds for 49ers vs. Cardinals in Week 18

Analyzing Sunday’s 49ers vs. Cardinals game with odds and lines, predictions and best bets.

The San Francisco 49ers (6-10) head to State Farm Stadium to take on the Arizona Cardinals (7-9) to close their 2024 NFL season.

The 49ers will look to end the season on an uptick before heading into an offseason with plenty of important decisions to be made. Brock Purdy’s future with the 49ers and whether or not an extension gets ironed out will be one of the primary storylines surrounding San Francisco’s offseason.

Any final evaluations of Purdy won’t happen on Sunday. Purdy is sidelined with a right elbow injury and the 49ers will turn to Joshua Dobbs as its starting quarterback.

In the two team’s first meeting this season, San Francisco built a 23-10 halftime lead before watching Arizona quarterback Kyler Murray rally the Cardinals back in the second half en route to a 24-23 Arizona victory.

As kickoff approaches, here’s a look at the betting odds, including the point spread, money line figures and the over-under point total. Plus, a prediction on how this one plays out.

49ers vs. Cardinals prediction, pick

Prediction: Arizona 27, San Francisco 20

Arizona has starting quarterback Kyler Murray as a go, while San Francisco will be without Brock Purdy. That’s enough to lean the Cardinals’ direction in this regular season finale.

Consider both Kyler Murray (+110) and 49ers running back Isaac Guerendo (+150) as anytime touchdown scorers. With several key pass-catchers potentially out of the equation and 49ers quarterback Brock Purdy as well, if San Francisco finds offensive success, there’s a good chance it’s Guerendo finding his way into the end zone.
