The 2025 NFL season heats up Sunday with a marquee NFC North matchup as the Detroit Lions face the new-look Green Bay Packers, who just signed star pass rusher Micah Parsons, to kick off the new football season. With high stakes and divisional tension, it’s a perfect spot for bettors to jump in with the best betting sites for NFL Week 1, offering over $4,000 in new-user sign-up promos ahead of kickoff.
BetMGM Sportsbook
CVRBONUS1500
BetMGM remains one of the best betting sites for NFL fans, and its Week 1 promo is perfectly timed for Sunday’s Lions vs. Packers showdown.
