Seeking to jump-start a woeful offense, the San Francisco 49ers have implemented some changes for Sunday night's matchup at the New York Giants.

Not surprisingly, offensive coordinator Geep Chryst would not reveal the specific adjustments made by the 49ers, who have scored a league-worst 48 points and been outscored 107-28 during a three-game losing streak.

"We made some major changes. I shouldn't say major. We made some adjustments that we feel good about going into this game," Chryst said per the San Jose Mercury News. "But it would be disingenuous for me to elaborate on it, and then we go out to the game and it's a clunker."

San Francisco's passing game ranks last in the NFL at 158.8 yards per game and quarterback Colin Kaepernick has thrown for only two touchdown passes against five interceptions while absorbing 14 sacks behind a struggling offensive line.

"We feel we've made some adjustments," Chryst added. "But I'd rather tell you next week what we did do than forecast what may or may not happen. It's the nature of the schemes and the game plan and the things coaches want to be protective of.

"But you have to go under the hood and correct things, tweak the engine so it runs a little more smoothly."
