Which team defeated the Las Vegas Raiders 18–12 in Week 3 of the 2026 NFL preseason?
Answer
San Francisco 49ers
The San Francisco 49ers defeated the Las Vegas Raiders 18–12 in Week 3 of the 2026 NFL preseason.
The game took place on August 27, 2026, during the final full week of exhibition games. San Francisco scored 18 points and held Las Vegas to 12, winning by six points in the preseason meeting between the two West Coast teams.
This result is distinct from San Francisco’s Week 2 victory over the Los Angeles Chargers. The 49ers also played Tennessee in Week 1, while the Raiders opened against Arizona and met Houston in Week 2. Keeping the opponent and week together helps avoid confusing the two Bay Area-area preseason schedules.
The final preseason week is often used to make last roster evaluations before regular-season cuts. Many players competing for backup roles or special-teams positions receive substantial playing time. The 49ers’ 18–12 victory therefore records the exhibition outcome without contributing to the regular-season standings.
