The Cleveland Browns largely shut down the San Francisco 49ers after giving up a touchdown on the opening drive in Sunday's 19-17 upset win.

"We say it all the time. We're the best in the world, as a defense and particularly as a secondary," Browns corner Greg Newsome II said.

The 49ers zoomed down the field, going 84 yards on five plays for an opening-drive touchdown. The Browns held San Francisco to 10 points and 161 yards of offense the rest of the way.

"We just came to the sideline (coach Jim) Schwartz was like, 'That's their only one,'" Newsome said of the first drive.

"Everyone just started doing their job, what we do every day at practice. They didn't give us anything new. They are a team that is going to stick to what they do. We just did our job, and we were successful."
