The returning Marshall Lynch inspired the Seattle Seahawks to a comprehensive 20-3 win over the San Francisco 49ers in NFL on Thursday.

Seattle suffered consecutive defeats in the last two weeks by squandering fourth-quarters leads, with both losses coming in the absence of injured running back Lynch.

But with Pro Bowl RB Lynch back in the line-up following a hamstring injury, the Seahawks made light work of the 49ers at Levi's Stadium.

The Seahawks (3-4) set the tone early with nine handoffs to Lynch on their opening drive. They quickly moved the ball into the red zone thanks to a 17-yard run by Lynch and a 16-yard pass to a wide-open Tyler Lockett. The drive stalled inside the 10, but Lynch was able to punch it into the end zone on a third-and-goal from the one to finish the 12-play, 61-yard drive. 

Lynch finished with 122 yards on 27 carries, running with power, excellent vision and showing no lingering effects of his injury with a nifty cutback on his long first-quarter run. 

The Seahawks nailed a 49-yard Steven Hauschka field goal and then extended their lead to 17-0 on a 43-yard touchdown strike from Russell Wilson to Lockett. The rookie from Kansas State, who already has a punt and kick return for touchdowns this season, got behind the 49ers secondary to grab his first career NFL touchdown reception. 

Lockett finished with five catches for 79 yards as Wilson had a big night against a 49ers defense that often left receivers wide open.

Wilson finished 18 of 24 for 235 yards with a touchdown and two interceptions and ran for 20 yards. 

San Francisco quarterback Colin Kaepernick, on the other hand, struggled mightily as the 49ers (2-5) gained just 55 yards of total offense in the first half without getting the ball past the Seahawks 40-yard line.

Kaepernick completed just 13 of 24 pass attempts for 124 yards and, when he missed, he missed badly. 

Led by Michael Bennett's three-and-a-half sacks, the Seahawks dropped Kaepernick six times and pressured him on nearly every drop-back. 

It was Seattle's first road win of the season, after dropping games in St Louis, Green Bay and Cincinnati.
