The Bengals needed the 49ers to beat the Chargers to help ensure Cincinnati makes it to the postseason if they are unable to win the AFC North.
Though San Diego fell behind 28-7, they would not go quietly into the night as they too were fighting for their postseason lives.
The 49ers got off to a fast start against San Diego after Frank Gore plowed through several Chargers on his way to the end zone to put San Fran up 7-0.
That's Brandon Flowers and Melvin Ingram crashing into him at the beginning of the run and Eric Weddle getting a stiffarm on gore's way to the 52-yard score, his longest of the season.
After Diego feel behind 28-7, the Chargers scored 14 straight to open the third quarter, highlighted by strip sack and score by the Chargers defense.
Right after committing the turnover, Colin Kaepernick responded with a 90-yard score, the second-longest rushing score by a QB in NFL history.
It looked like the 49ers had control with a two-score lead with under six minutes to go, but the Chargers scored 14 straight in the final 5:15 of the game to send the game into overtime.
San Francisco turned the ball over on their first overtime possession after receiver Quinton Patton fumbled the ball at the 40-yard line of San Diego where they recovered it.
From there, San Diego moved right down the field before Nick Novak booted in the 40-yard game-winning field goal to seal the win.
