Everyone remembers the "Big Dom" incident. You know, the moment when an Eagles security chief and a 49ers linebacker both got tossed from the sideline like they were in a Friday night bar scuffle. But honestly, if you only focus on the drama, you’re missing why the 2023 49ers vs eagles regular-season matchup was actually a masterclass in psychological warfare.
The Niners didn't just win that game on December 3, 2023. They systematically dismantled the aura of the Philadelphia Eagles.
It was a cold afternoon at Lincoln Financial Field. The Eagles were 10-1, the darlings of the NFC, seemingly unstoppable. San Francisco arrived with a chip on their shoulder the size of the Golden Gate Bridge, still fuming about the NFC Championship game from the year before where they literally ran out of healthy quarterbacks. They wanted blood. They got it. 42-19.
The Game Where Brock Purdy Silence the Doubters
For months, people called Brock Purdy a "game manager." They said he was just a passenger in Kyle Shanahan’s expensive Ferrari.
Then this game happened.
Purdy went 19-of-27 for 314 yards and four touchdowns. No interceptions. No "rookie" mistakes. He was surgical. He didn't just check the ball down to Christian McCaffrey; he pushed it. He found Brandon Aiyuk in the back of the end zone. He threaded needles to George Kittle.
By the time the fourth quarter rolled around, the Philly crowd—arguably the most hostile in sports—was quiet. That’s hard to do. Purdy’s efficiency rating was off the charts, but it was his poise that stood out. While Jalen Hurts was under constant duress from a relentless Niners defensive line (Arik Armstead and Javon Kinlaw were basically living in the backfield), Purdy looked like he was playing a 7-on-7 drill in July.

Deebo Samuel Backed Up the Talk
Deebo Samuel spent the entire offseason and the weeks leading up to this game talking. A lot. He called the Eagles "trash" after the previous playoff loss. He said the only reason Philly won was because the Niners didn't have a QB.
Most players who talk that much end up eating their words. Deebo? He ate the Eagles' secondary instead.
- Rushing TD: A 12-yard sweep where he looked like a bowling ball hitting pins.
- Receiving TD 1: A 48-yard catch-and-run where he forced missed tackles like they were optional.
- Receiving TD 2: A 46-yard dagger that officially turned the game into a blowout.
Three touchdowns. 138 total yards. He was the "wideback" in his purest form. When Deebo is on, there is no defensive scheme in the NFL that can account for his combination of speed and sheer violence at the point of contact.
The "Big Dom" Side Show and Why It Mattered
We have to talk about it. Third quarter. Dre Greenlaw tackles DeVonta Smith near the Eagles' sideline. It was a hard hit, maybe a little extra on the end, but nothing insane for NFL standards.
Then came Dom DiSandro.
"Big Dom," the Eagles' head of security, stepped in to separate the players. Greenlaw didn't like a non-player getting in his kitchen and ended up making contact with DiSandro’s face. Both were ejected.

People think this helped Philly because they "lost" a linebacker while the Eagles only lost a staffer. Kinda the opposite, actually. The 49ers fed off that chaos. It galvanized them. Instead of losing their cool, they turned that "us against the world" energy into 21 unanswered points. It showed a level of emotional maturity that many didn't think this Niners team had.
49ers vs Eagles 2023: By the Numbers
If you look at the box score, the disparity is wild. Philly actually started strong, leading 6-0 after the first quarter. But then the wheels didn't just fall off; they exploded.
The Niners scored touchdowns on six consecutive drives. Think about that. Against a defense featuring Fletcher Cox and Jalen Carter, San Francisco simply decided they weren't going to punt anymore.
Key Stats from the Matchup:
- First Downs: SF 22, PHI 22 (Surprisingly even, but misleading).
- Total Yards: SF 456, PHI 333.
- Third Down Efficiency: SF was 8-for-11. They were basically automatic.
- Red Zone: SF went 4-for-4. They didn't settle for field goals once they got close.
Jalen Hurts finished with 298 yards and a rushing score, but he looked human for the first time in months. The 49ers' defense, led by Fred Warner, took away the middle of the field and dared the Eagles to beat them on the outside. Without a consistent run game—D'Andre Swift was held to just 13 yards on 6 carries—the Eagles' offense became one-dimensional.
Why This Game Was the Turning Point for Both Teams
The 2023 49ers vs eagles game wasn't just a mid-season fluke. It was a preview of the downfall of Philadelphia's season. Before this game, the Eagles looked like the clear favorites for the Super Bowl. After this game? They went on a tailspin, losing five of their last six regular-season games and getting bounced in the first round of the playoffs by Tampa Bay.

The Niners, on the other hand, proved they were the "big bad" of the NFC. They showed that when healthy, their roster is essentially a Pro Bowl team disguised as a franchise.
It also settled the "who's better" debate for the 2023 season. While Philly fans will always point to the 2022 NFC Championship, the 2023 regular-season meeting was the fair fight everyone wanted. And in that fair fight, San Francisco wasn't just better—they were in a different league.
Actionable Takeaways for the Next Matchup
If you're betting on or analyzing the next time these two giants meet, keep these things in mind:
- Watch the Trenches: The Niners won because their defensive line neutralized Jalen Hurts' ability to scramble early. If you can keep Hurts in the pocket, you win.
- The Deebo Factor: Philly’s secondary struggled with "bully ball." Any team with a physical YAC (Yards After Catch) receiver is going to give the Eagles' defensive scheme fits.
- Poise over Noise: Lincoln Financial Field is loud, but the 2023 Niners proved that a focused offense can use that noise to simplify their communication and go on a tear.
The 2023 showdown remains a landmark game because it stripped away the excuses. No injuries at QB. No weather issues. Just two heavyweights in the ring. One walked out. The other was never the same for the rest of the year.
Assess the current roster health of both teams before their next meeting; history shows that for the Niners, being at 100% makes them nearly impossible to scheme against, while the Eagles' defensive secondary remains their biggest "X-variable" in high-stakes games.
