Knowing his job security is on a week-to-week basis doesn't faze San Francisco 49ers quarterback Blaine Gabbert.

"The biggest thing for me is I focus on this upcoming game. That's how I approached last (game)," Gabbert said. "You can't get too far ahead of yourself, especially in the situation we're in. Whatever happens after that, will happen."

Gabbert was elevated to starter when coach Jim Tomsula benched Colin Kaepernick on Nov. 2 following a second straight lackluster performance in a 27-6 loss at St. Louis.

Making his first start in more than two years, Gabbert guirded the 49ers to a 17-16 victory over the Atlanta Falcons. He threw for 185 yards on 15-of-25 passing with two touchdowns and two interceptions to snap a 10-game losing streak.

Gabbert now must face a Seahawks squad that has limited San Francisco to two touchdowns over the past five regular-season meetings.

"When you look at film, yes, they have talented guys on the defensive line. Yes, they have talented guys in the secondary," Gabbert said. "But, we're focused on ourselves this week and want to go out there and execute at a high level."
