It wasn't -- somewhat surprisingly -- made a primetime matchup, given the fact that the Cardinals and Panthers met in the NFC Championship game. But the Oct. 30 game in Carolina was given the late kickoff -- 1:25 p.m. Arizona time, 4:25 p.m. in North Carolina -- ostensibly so it could be showcased on Fox.
Then the Cardinals had their issues with a 2-3 start and the Panthers have struggled mightily, falling to 1-4 after a "Monday Night Football" loss at home against the Buccaneers. So maybe it shouldn't have been a surprise when Wednesday the NFL officially moved the Cards-Panthers kickoff, up to 10 a.m Arizona time. The Falcons (who are playing well and lead the NFC South) host the Packers that day in a game that was originally at 10 a.m. Arizona time and now gets that open 1:25 p.m. slot on Fox.
What it means is a much earlier start for the western team, and the one game the Cardinals had with such a time this season didn't go so well (an ugly loss in Buffalo.) The Cards will leave on Friday that weekend to try and get acclimated, but it is an early start.
(Then again, the Cards got a night start in Carolina in January, and that didn't turn out well either. So ...)
