Geno Smith remains confident in the Seattle Seahawks' offense despite another ineffective performance in Thursday night's 31-13 loss to the San Francisco 49ers.

Seattle managed just 220 yards, went 3-for-11 on third down and failed to score an offensive touchdown.

They've gone seven straight quarters without a touchdown and have just three over their past four games.

"I still believe in our coaches," Smith said. "I still believe in our players. I think it's been a tough stretch for us, but I believe that things will turn around. I think what we have to do is continue to work hard, if not work harder. There is no excuse for it. There is no words that I can say that will make it better, but what needs to be done is we need to work harder. We need to find a way. We've got a lot of talent. We've got a lot of good players on this offense and we've got the right coaches. So we've got to believe."

In response to a question about whether he'd change anything with the game plan in retrospect, Smith backed offensive coordinator Shane Waldron.

"I feel like Shane always does a great job and I've got his back 110 percent," Smith said. "He knows that. I feel like it comes down to us executing better as players. No matter what the play is called, it comes down to the players making it come to life. So Shane's called some great games for us and he's going to continue to do that. I just think overall we've got to stay confident, we've got to keep believing in what we're doing, keep believing and trusting our process and Shane's going to continue to call great plays and we've just got to execute for him."

Smith was also playing just four days after suffering a triceps contusion.
