49ers game today vs. Cardinals: Week 4 injury report, spread, over/under, schedule, live stream, TV channel

The 49ers host the Cardinals for a Week 4 NFC West showdown at Levi's Stadium, and Niner Noise has all the details you'll want to know about the game.

The undefeated San Francisco 49ers have a chance to start off the first quarter of the 2023 season with a perfect 4-0 record, and pulling off a victory over the visiting Arizona Cardinals this Sunday will also give head coach Kyle Shanahan's squad two victories within the NFC West.

Those may come in handy down the stretch when looking at the divisional standings and who will take the top spot.

That's a long way away, though, and the Niners are much more focused on ensuring first-year head coach Jonathan Gannon's inaugural trip to Santa Clara, California, in his new role is a sour one.

But Arizona just pulled off a shocking upset over the Dallas Cowboys last week, and Gannon would love nothing more than to get his 1-2 Cardinals back to the .500 mark by beating a division rival, one he helped the Philadelphia Eagles to defeat in the NFC Championship game when he was the defensive coordinator there.

That'll probably be a storyline for Sunday's contest.

Let's break down the latest betting odds, injury report, ways fans can tune into the game live and more!

49ers injury report vs. Cardinals Week 4

After some initial concerns during the week, it appears as if both wide receivers Brandon Aiyuk (shoulder) and Deebo Samuel (ribs, knee) will be available for the contest, the latter being reported as such by ESPN's Adam Schefter early on Sunday morning.

San Francisco is, however, dealing with a few other notable injuries as Schefter pointed out, and here are those named on the team's Week 4 injury report:

• LB Dre Greenlaw (ankle): Questionable
• WR Jauan Jennings (shin): Doubtful
• WR Deebo Samuel (ribs, knee): Questionable
• LB Demetrius Flannigan-Fowles (ankle): Questionable
• RB Elijah Mitchell (knee): Questionable

Arizona also ruled out defensive end Jonathan Ledbetter and linebacker Josh Woods for the game.
