Week 2 of the NFL saw several top teams struggle, with the 49ers, Cowboys, and Ravens facing unexpected losses. The 49ers' defeat was marked by a missed fourth-down conversion and a historic 97-yard touchdown allowed to Justin Jefferson, while the Ravens faced their first 0-2 start since 2015, prompting coach John Harbaugh to insist the team's season is not over. Meanwhile, the Chiefs narrowly defeated the Bengals thanks to a last-second field goal, and the Texans managed to hold off the Bears for a close victory. In roster news, the 49ers placed star running back Christian McCaffrey on injured reserve due to Achilles tendinitis, raising concerns about the team's offensive capabilities moving forward. Additionally, Malik Willis is set to start for the Packers in their upcoming game against the Colts following Jordan Love's injury designation, though expectations for his performance remain tempered. As teams navigate these challenges, the competitive landscape of the NFL continues to evolve.
