The countdown to the 2026 NFL season is officially on, and for Arizona Cardinals fans, the schedule puzzle is starting to take shape—even before the full slate drops this Thursday. While the team hasn't made any official announcements yet, the week's early leaks of national TV matchups are already giving us a clearer picture of what's to come.

One key detail has emerged: the Detroit Lions will be heading to the desert to face the Cardinals in 2026, but it won't happen in Week 2. That's because the Lions have just been booked for a Thursday night road game against the Buffalo Bills in Week 2, serving as the Bills' grand home opener at their brand-new Highmark Stadium.

So while the Cardinals-Lions clash is still on the docket for this season, fans will have to wait a little longer for that NFC showdown at State Farm Stadium. It's a matchup that promises plenty of excitement, especially as both teams continue to build their rosters and identities.

Mark your calendars: the full 2026 NFL schedule will be released this Thursday at 8 p.m. ET. Until then, keep an eye on those leaks—they're giving us a sneak peek at the road ahead. And if you're looking to gear up for the season in style, make sure you're stocked with the latest Cardinals apparel to show your support from kickoff to the final whistle.
