Niners flop, Jed York apologizes

Staff/wire report

SANTA CLARA, Calif.

Richard Sherman set up the only touchdown with another key defensive play in this heated rivalry, then made a second interception with the 49ers driving late, and the Seattle Seahawks ended a five-game losing streak on San Francisco’s home field with a 19-3 win Thursday night.

Steven Hauschka kicked four field goals and the Seahawks’ stout defense held Colin Kaepernick and Michael Crabtree in check as Seattle (8-4) overcame 14 penalties for 105 yards, including an offensive pass interference that negated a touchdown.

Russell Wilson passed for 236 yards and thoroughly outplayed Kaepernick, who had one of his worst performances for the 49ers (7-5).

Forty-niners owner Jed York, a Cardinal Mooney High graduate, apologized to fans on Twitter.

“Thank you #49ersfaithful for coming out strong tonight. This performance wasn’t acceptable. I apologize for that,” York tweeted.

After his second pick, Sherman looked at those fans still remaining in half-empty stadium on a Thanksgiving night and gave them the hush sign with his pointer finger to his mouth, then waved goodbye. The Seahawks won by the identical score they beat first-place Arizona four days earlier.

Kaepernick was just 16 for 29 for 121 yards.

The 49ers have won five straight home games in the rivalry, but this marked Seattle’s first trip to new $1.3 billion Levi’s Stadium.

San Francisco wide receiver Michael Crabtree went down 56 seconds into the game after landing awkwardly on his left side after a tackle by safety Kam Chancellor. Crabtree later returned.
