SANTA CLARA, Calif. – Russell Wilson high-stepped his way down the sideline before hugging coach Pete Carroll after Jason Myers' kick split the uprights.
After a wild overtime, the Seahawks had knocked the Niners from the ranks of the unbeaten and made sure the NFC West would remain tight down the stretch.
Myers kicked a 42-yard field goal after rookie Chase McLaughlin missed a kick earlier in overtime, and the Seahawks handed the 49ers their first loss with a 27-24 victory on Monday night.
"That was the craziest game I've ever been a part of," Wilson said.
Myers gave Seattle (8-2) its second consecutive overtime victory after Wilson got the Seahawks into position with an 18-yard scramble on third-and-3. Myers delivered one week after missing two field goals and an extra point, moving Seattle on the heels of San Francisco (8-1) in the NFC West.
"We practice these situations every day," left tackle Duane Brown said. "Russell Wilson is the best quarterback in the league. When you have him under center, I don't care how much time is on the clock. We feel like we have a chance."
The Seahawks blew an opportunity to win the game on the opening possession of overtime when Wilson was intercepted at the Niners 4-yard line by Dre Greenlaw, who returned the ball 47 yards to the Seattle 49. The 49ers moved the ball 20 yards before McLaughlin, who briefly was on the Vikings practice squad this season, missed badly to the left on a 47-yard attempt. McLaughlin had made a 47-yarder at the end of regulation to tie the score at 24-24.
The teams then traded punts. The Seahawks took over at their 36 with 1:25 remaining after Jimmy Garoppolo threw three incompletions as San Francisco burned only 14 seconds off the clock with Seattle out of timeouts.
"Definitely wish we had taken more time off the clock, but was counting on us catching one of those balls," 49ers coach Kyle Shanahan said.
