The Chicago Bears pulled off the early upset of the NFL seasons, scoring 19 unanswered points to take down the San Francisco 49ers at home on Sunday. 

It was quarterback Justin Fields who led the way in this comeback victory. Playing in the pouring rain, Fields only threw 17 times, connecting on just eight of them for 127 yards. But those connections were big ones, especially the 51-yard bomb to wide receiver Dante Pettis that made it a 10-7 game in favor of San Francisco. 

It's the throw that got the Bears back in the game, as both teams weren't doing well offensively.

Niners quarterback Trey Lance didn’t help matters after that touchdown from Fields. The next drive ended after just six plays, and Chicago capitalized with a 10-play drive to take the lead, 13-10, after Fields found Equanimeous St. Brown for an 18-yard score.
