San Francisco 49ers quarterback Colin Kaepernick is unfazed by his uninspiring start to the NFL season, insisting he does not play for job security.

Kaepernick has struggled to make an impact in his past two games for the lowly 49ers, completing just 22 of 44 passes for no touchdowns and has had five interceptions, which were returned for TDs.

The 27-year-old, however, was quick to squash any rumblings about his position in San Francisco.

"I don't play for job security," Kaepernick said on Wednesday.

"Whether football is here or not, I will be fine. I go out, I play to win. I'm not worried about job security when I step in this building."

According to head coach Jim Tomsula, he had a sit down with Kaepernick and told him to stop second-guessing himself.

"If you are, stop," Tomsula said. "Can't have it. Can't play that way.

"Don't play not to make a mistake; Just play. Play to make the play."

Now the 49ers (1-3 in the NFC) will face the New York Giants on Sunday, and neither quarterback nor coach wants to be in the position they have been in the past three games.

"Just play to win," Kaepernick recalled of Tomsula's advice. "If something happens, it happens. But we have to go out and make sure we're making plays.

"It's something that you're going to have that in the back of your mind. You're going to make sure that you protect the football. I put our team in a bad situation in the Arizona game. I wasn't going to allow that to happen again."
