SEATTLE -- The Seattle Seahawks ended a two-week drought with their first win of the season Sunday, when they shut out the Chicago Bears 26-0 and doused first-year defensive coordinator Kris Richard with a Gatorade bath. But the celebration pretty much stopped there.

"I'm not going to say we're back," linebacker K.J. Wright said after Seattle held the Bears (0-3) to just 146 yards and seven first downs. "We've got to keep working. You can't say we've arrived or we're the best defense in the NFL just like that. We've still got a lot of work to do."

Tight end Jimmy Graham made a splash in his home debut and safety Kam Chancellor returned to spearhead a solid defense that recorded its first shutout since Week 15 of the 2013 season.

"He was very comfortable; they were comfortable with him in there," coach Pete Carroll said. "You could just see it. He made us whole."

Seattle also overcame a hamstring injury to star running back Marshawn Lynch, whose absence was minimized by a breakout performance from rookie Thomas Rawls. The undrafted rookie from Central Michigan had 104 yards on 16 carries.

Lynch was unavailable at the start of the game and carried just five times for 14 yards before coming out with a hamstring injury he suffered late in the first half.

"It's nothing to be alarmed by," Carroll said after the win. "We'll just have to wait and see."

Graham scored a 30-yard touchdown in the third quarter of his first home game as a Seahawk, giving Seattle a 20-0 lead after the offense struggled through most of the first half.

Seattle kicker Steven Hauschka made four field goals, the first two of which came during a first half that saw the Seahawks struggle on the way to a 6-0 lead. Special teams helped spark Seattle, as Richard Sherman's 64-yard punt return set up the first Hauschka field goal before rookie Tyler Lockett broke a franchise-long 105-yard kickoff return for a touchdown to open the second half while giving the Seahawks (1-2) a 13-0 lead.

"I don't think anybody touched me at all," Lockett said. "It was just me and the kicker (Robbie Gould), and then I just had to make sure I didn't get caught from behind."

Said Chicago coach John Fox: "It wasn't a great way to start the second half."

Graham, who had seven receptions for 83 yards, opened up the game with the 30-yard touchdown reception with 4:28 remaining in the third quarter.

Chicago quarterback Jimmy Clausen, starting in place of injured Jay Cutler, completed 9 of 17 passes for 63 yards as the Bears fell to 0-3 for the first time since 2003.

"We just couldn't generate anything," Fox said.

Seattle quarterback Russell Wilson completed 20 of 30 passes for 235 yards and the touchdown.

Seattle's offense, which was without Lynch for most of the first quarter, sputtered but was able to go into halftime with a 6-0 lead on a pair of Hauschka field goals. A 64-yard punt return on a trick play that left Sherman with open field in front of him, set up Hauschka's first field goal for a 3-0 Seattle lead in the first quarter. The Seahawks put in their first sustained drive of the half over the final two minutes of the second quarter, resulting in another Hauschka field goal after Chicago cornerback Alan Ball knocked away passes on consecutive plays in the end zone.

The Seahawks scored two touchdowns over the first 10 1/2 minutes of the second half to put the game out of reach.

"Honestly, I don't think the game every got out of hand," Sherman said.
