WATCH: Nick Bosa drops Geno Smith for drive-ending sack

WATCH: Nick Bosa runs through Seahawks LT for sack.

The 49ers defense let Seattle cruise to San Francisco’s 35 to start the second half, but on a third-and-medium Nick Bosa put an end to the Seahawks hopes of scoring. He blew past Seattle’s left tackle Stone Forsythe and dragged down Geno Smith for a sack. That not only ended the drive, but pushed the Seahawks out of field goal range and forced a punt.
