Wilson's TD passes lift Seattle

Rookie QB throws for four scores as Seahawks romp to clinch playoffberth

Russell Wilson threw four touchdown passes to move into second place for TD passes by a rookie, Marshawn Lynch scored twice, and led by their rocking crowd the Seattle Seahawks clinched a spot in the NFC playoffs with a 42-13 rout of San Francisco on Sunday night.

Wilson threw touchdowns to Lynch, Anthony McCoy and two in the second half to Doug Baldwin to give him 25 for the season, one shy of Peyton Manning’s record of 26.

Lynch added 111 yards rushing and a 24-yard TD run on Seattle’s opening drive that set the tone.

Richard Sherman returned a blocked field goal 90 yards for a touchdown and added an interception as the Seahawks (10-5) jumped to a 21-0 lead.

Colin Kaepernick and the 49ers (10-4-1) struggled with the deafening noise echoing around CenturyLink Field, making for a miserable 49th birthday for 49ers coach Jim Harbaugh.

Most likely Seattle will be the No. 5 seed in the NFC. There remains a slight chance of winning the NFC West if the Seahawks beat St. Louis in the season finale and Arizona upsets the 49ers in San Francisco.

San Francisco tight end Vernon Davis left the game with a concussion after getting hit along the sideline by Seahawks safety Kam Chancellor.

Davis was attempting to haul in a pass deep in Seattle’s end late in the first quarter.

Davis caught the pass but was immediately knocked off his feet by Chancellor, jarring the ball loose. Davis was slow to get up, was examined by doctors on the sideline and eventually taken to the locker room for further evaluation. He did not return.

Davis had one catch for 27 yards in the first quarter.

The 49ers also lost wide receiver Mario Manningham to a left knee injury in the third quarter when he was hit low by Seattle linebacker Leroy Hill and fumbled before he hit the turf.

Manningham was on the ground for several minutes before being helped off the field and being taken to the locker room on a cart.
