Get in on an NFC West rivalry matchup as the Seahawks take on the Cardinals at 8:15 p.m. ET on Prime Video. The Seahawks come into this game 2-1, and could easily be 3-0 without a late game loss to the 49ers. However, with the 49ers banged up, the Seahawks can stay in the NFC West hunt with a win tonight.
On the other side, the Cardinals are tricky to figure out. While Kyler Murray is a staple of the franchise, Marvin Harrison Jr. has been disappointing thus far as the top wide receiver. With this, the Seahawks are slight 1.5-point road favorites for Thursday Night Football.
