Tennessee Titans @ San Francisco 49ers 12/14/2025
Week 15 brings us a cross-conference tilt in Santa Clara as the Tennessee Titans visit the San Francisco 49ers at Levi’s Stadium on Sunday at 4:25 PM ET. If you’re lining up a bet for this one, think pace, matchups, and motivation. San Francisco has been stacking wins behind Kyle Shanahan’s structured offense and a defense that’s playing fast and opportunistic. The 49ers just handled business against Cleveland and come in well-positioned in the NFC West race. Tennessee, meanwhile, finally saw some life last week, popping for 31 on the road behind a revived ground game and timely takeaways. Still, the broader arc of their season under Brian Callahan has been rocky.
On a per-game basis, this sets up as a clash of profiles: San Francisco averages about 23.6 points while allowing 20.7, a disciplined +2.9 average margin. Tennessee sits around 15.5 points scored and 27.5 allowed, a -12.0 average margin that’s been tough to shake. With clear skies and mild temps in the Bay, we’re looking at a cleaner offensive environment—but with injuries to key Niners stars and a Titans team that can shorten the game with the run, this number has to be respected. Let’s dive into our picks.

Our betting predictions: Tennessee Titans @ San Francisco 49ers
Best Bet: Under 45.5 Points
Primary pick: Under 45.5 points at -125 with Fanatics Sportsbook. Projection: 56% chance the game stays Under (break-even ~55.6% at -125). The Niners have been more methodical at home (about 20.6 points per game at Levi’s), and their defense, even banged up, has kept scores manageable. Tennessee’s offense averages just 15.5 per game overall and around 14.8 on the road. Add in a Titans approach that leans on the run and ball control when they can, and this has a strong path to an Under.

Tip 2: Spread – 49ers -11.5
2) Spread: 49ers -11.5 at -125 with Fanatics Sportsbook. Projection: 54% cover probability. San Francisco’s average margin sits near +3 across the season, but that’s weighed down by some injury-laden weeks and tougher road slates. At home, they’re the more efficient and balanced team. Tennessee’s average margin is around -12.0, and they’ve struggled to sustain drives on the road. With Shanahan scripting the early series and a rested staff dialing up the matchups, San Francisco has the path to pull away.
Tip 3: Moneyline – 49ers to win
3) Moneyline: 49ers to win at bet365 (implied ~89%). Projection: 89% win probability, matching the market range. This is the safer leg if you’re building a parlay or anchoring exposure. San Francisco has a material coaching and efficiency edge, and while the Titans have a bit of juice off last week’s win, the gap in per-game performance is still wide.
San Francisco snapshot: steady, structured, and built to close
Under Kyle Shanahan, the 49ers are 9-4 and trending toward January football. Within the NFC West, they’re firmly in the division title mix and in strong shape for a playoff berth. On average, they’re scoring about 23.6 per game while allowing 20.7, a tidy +2.9 margin. At Levi’s Stadium, they’ve been more controlled and lower-scoring: roughly 20.6 points scored and 20.4 allowed per home game, which fits the Under angle.
Recent form? Four wins in their last five, including a 26-8 performance in their most recent contest—emphatically low-scoring and defense-forward. Brock Purdy stabilized after a turnover-heavy week, George Kittle remains the chain-mover, and Christian McCaffrey’s usage consistently sets the floor for efficiency, even if the yards don’t balloon. With Brandon Aiyuk’s knee issue and key defensive injuries (Nick Bosa, Fred Warner) in the headlines, San Francisco’s identity has leaned into discipline and situational football. That’s how they keep pressure on opponents and nudge games into their preferred tempo.
Tennessee snapshot: flashes of pop, but too many uphill drives
Brian Callahan’s Titans are 2-11 and battling from the bottom of the AFC South. The averages tell the story: about 15.5 points per game on offense and 27.5 allowed, a -12.0 average margin that’s put them behind the sticks early and often. On the road, they’re around 14.8 points scored and 25.7 allowed—still a negative delta, but slightly tighter splits than at home.
There was real momentum last time out: a 31-29 road win behind a big day on the ground and a pair of takeaways. Tony Pollard exploded for his best rushing output of the season, and the Titans finally stacked enough positive plays to get across the line. That said, sustaining that production against a better-coached, more balanced defense on the road is a higher bar. The Titans’ path here is long drives, field position, and protecting the ball—because asking them to chase 24+ against San Francisco’s structure is exactly where games tilt away from them.
Keyplayer Statistics/Momentum/External Factors
- Quarterbacking: Brock Purdy rebounded with efficient football, keeping mistakes off the sheet and finding George Kittle in money downs. That playstyle pairs well with a Titans defense that can be stressed horizontally by Kyle Shanahan’s motion packages.
- Playmakers: Christian McCaffrey’s touch profile keeps the offense on schedule. For Tennessee, Tony Pollard’s Week 14 surge is the blueprint—early rushing success to help a young passing game.
- Injuries: San Francisco’s injuries to Brandon Aiyuk (knee) and stars like Nick Bosa and Fred Warner matter, but the scheme is built to absorb absences. Kicker Eddy Piñeiro’s expected return provides stability in close-and-late spots.
- Environment: Clear skies, about 66°F, and a friendly Levi’s surface favor the more efficient team—edge Niners. Travel and short-term morale do add a nudge for Tennessee, but not enough to shift the core handicap.
Last direct match
Last head-to-head: Tennessee 17-13 at home. The Titans took a tight one, but both rosters and contexts have shifted since.
Performance last 5 Matches
- San Francisco: 4 wins, 1 loss.
- Tennessee: 1 win, 4 losses.
Division context and playoff lens
- NFC West: The 49ers are right in the chase for the division crown and lining up postseason seeding. With seven playoff spots per conference (four division winners, three wild cards), seeding leverage matters in December.
- AFC South: Tennessee sits at the bottom of the division and is focusing on development, evaluation, and building blocks for 2026. There’s still fight in this roster, but the margin for error is razor-thin against top-tier NFC competition.
Why are our numbers like the Under and Niners to control
This matchup skews toward a structured, methodical game. San Francisco’s home scoring average (about 20.6) plus Tennessee’s road average (about 14.8) lands near 35-38 combined points on a neutral read—comfortably below 45.5, even allowing for variance. The 49ers’ defense, despite high-profile injuries, has kept scores tamped down and turned the field position battle their way. Tennessee’s offense is more likely to shorten the game with the run than to push this into a track meet.
For the spread, the gap in per-game margins (-12.0 Titans, +2.9 Niners) and San Francisco’s structural edges lead us to a modest-edge cover probability (about 54%) at -125. The moneyline is the confidence leg: around an 88% win chance, making it a solid anchor but not the best standalone value.
TrustnBet Final Thoughts
Under 45.5 at -125 is our top play. The pace profiles, defensive structure, and home/road scoring splits point to a lower total. Our projection (56% Under) edges the break-even. – 49ers -11.5 at -125 is next. San Francisco’s coaching, efficiency, and situational edge should tell late, even with injuries. We’re at about a 54% cover probability. The 49ers’ moneyline is the safest angle if you’re pairing bets or building a parlay, with an 88% win probability in our read.
Add it up, and we’re backing a measured Niners home performance—more method than mayhem—against a Titans team that needs too many things to break right on the road. Our card: Under 45.5, 49ers -11.5, and Niners to win outright.
