The Browns stunned the undefeated 49ers on Sunday with a late fourth quarter drive and hung on for the 19-17 win after a missed field goal by San Francisco.

After forcing a three-and-out with just under 3 minutes to play, the Browns got the ball back down one point to the undefeated 49ers. Starting at their own 20-yard line, the Browns marched their way down the field. QB P.J. Walker threw two incomplete passes on the first two downs, and on the third, the 49ers had a penalty that moved the ball to the 41-yard line and gave the Browns a first down.

RB Jerome Ford ran for 13 yards on the ensuing play and put the Browns at the 50-yard line. After a defensive holding penalty helped move the chains again, Ford ran for 22 yards to give the Browns another first down in the red zone. The Browns stalled from there but set up Dustin Hopkins for a 29-yard field goal.

The Browns almost watched their lead slip away, but the 49ers' 41-yard field goal attempt with 9 seconds to play missed wide right.

The Browns improved to 3-2 on the season, while the 49ers lost their first game of the season and are 5-1.

Key moments:

Sunday's game was filled with key moments on both sides of the ball. The final defensive stop on the 49ers' final drive to force a field goal attempt was the epitome of what the Browns were able to do defensively all throughout the game.

The Browns defense continued to excel on Sunday. With about 10 minutes left in the third quarter, Martin Emerson Jr. intercepted a pass from 49ers QB Brock Purdy and returned the interception for 13 yards. Not only was it Emerson's first career interception, but it was also Purdy's first interception of the season. It served as a momentum swing for the Browns in Cleveland Browns Stadium. The Browns defense continued to excel throughout Sunday's game.

Offensively, RB Kareem Hunt's 16-yard touchdown run to put the Browns on the board. The Browns snapped the ball directly to TE Harrison Bryant, who pitched the ball to Hunt, and Hunt found a hole to run right into the end zone. As the Browns celebrated their first touchdown of the game, the sun broke through the clouds and illuminated Cleveland Browns Stadium in sunlight.

Then, Hopkins' game-winning field goal from 29 yards out sealed the win for the Browns. They put Hopkins in great field position in the red zone for the kick, and as the ball soared through the uprights, the crowd erupted in cheers.
