In a tightly contested matchup, the Baltimore Ravens narrowly defeated the San Francisco 49ers 20-17 in Week 1 of the 2027 season. With both teams hungry to establish their dominance early in the year, the Ravens emerged victorious in a game that showcased their resilience and ability to perform under pressure. Lamar Jackson led the Ravens' offense, throwing for one touchdown while managing the game effectively, but it was Derrick Henry's ground game that made a significant impact, racking up 90 rushing yards. On the other side, Brock Purdy posted impressive numbers with 235 passing yards, finding his favorite target, Deebo Samuel Sr., who accumulated 101 receiving yards, keeping the 49ers competitive throughout the contest. Defensively, the 49ers were bolstered by Dre Greenlaw's seven tackles and Nick Bosa's sack, but it was the Ravens' ability to make critical stops in the second half that ultimately sealed the victory. The turning point came late in the fourth quarter when Baltimore's defense forced a crucial three-and-out, allowing their offense to run down the clock and secure the win.
