How to watch Seahawks-Cardinals for free

Week 4 of the 2025 NFL season is kicking off with an NFC West clash when the Seattle Seahawks head south to take on the Arizona Cardinals.

Both teams are currently 2-1, with their one loss both coming from the same division rival; in Week 1, Seattle fell to San Francisco, and in Week 3, the 49ers mounted a 10-point comeback to beat the Cardinals.

A win tonight would be major for either team, with the losing team falling to 0-2 in divisional play.

Ahead of kickoff, the line for tonight’s game has bounced around, with oddsmakers having a tough time separating the evenly-matched teams.
