DETROIT (AP) The San Francisco 49ers did what they could to keep the Detroit Lions in the game before making just enough plays for a rare 2 game winning streak.
Frank Gore set a franchise record with 148 yards rushing in the 1st half and scored on a 61 yard run before leaving the game with a concussion, and Joe Nedney made all 4 of his field goal attempts to give San Francisco a 19-13 victory over Detroit on Sunday.
Keith Lewis intercepted Jon Kitna's pass at the 49ers 2 with 2 1/2 minutes left and San Francisco (4-5) picked up the one 1st down it needed to seal the game, winning consecutive games for the second time since 2003.
Gore finished with career high 159 yards rushing, leaving the game stumbling to the sideline late in the 3rd quarter after catching a pass.
San Francisco's Alex Smith was 14-20 for 136 yards with a fumble. Arnaz Battle caught 6 passes for 55 yards, and converted a 3rd down on the final drive to allow the 49ers to run out the clock.
The Lions (2-7) had a chance to win consecutive games for the first time in nearly 26 months and the third time since 2001, when Matt Millen took control of the franchise.
Jon Kitna was 19-30 for 202 yards with a touchdown, interception and fumble. Kevin Jones accounted for 115 yards rushing and receiving and wide receiver Roy Williams was limited to 81 yards receiving.
The 49ers entered the game giving up an NFL high 30 points a game, and an average of 40 in their previous three road games, but they shut down Detroit's Mike Martz directed offense a week after limiting Minnesota to 6 points.
San Francisco led 13-3 at halftime after scoring on 3 of its first 4 drives, probably wishing it had a bigger lead after outgaining Detroit 247-102 and recovering a fumble without giving up a turnover.
The 49ers had chances to go ahead big in the 3rd quarter because Detroit had 2 turnovers on its first 3 plays, but they came away with only a field goal and a 13 point lead.
Smith's fumble midway through the 3rd quarter set up a score that helped the Lions get back in the game. Kitna rolled right, then went back to his left and lofted an 8 yard pass to Dan Campbell to make it 16-10.
Gore then caught a 7 yard pass, wobbled off the field and did not return. The 49ers drove down the field to set up Nedney's 4th field goal, a key score because it made Detroit go for a TD instead of kicking a tying field goal late in the game.
Jason Hanson made a field goal on the ensuing drive, making it 19-13 in a game marred by missed opportunities by both teams.
Gore started his day with a big run. On one of Gore's many draws, he squirted away from a few Lions on the left side and cut across the field for a 61 yard TD.
After Jones fumbled, Nedney's 28 yard kick gave the 49ers a 10-0 lead.
San Francisco added to its cushion early in the 2nd quarter with another Nedney field goal two plays after Smith's threw directly at cornerback Stanley Wilson, who likely would've scored had he simply caught the ball.
The Lions showed some signs of life on their last drive in the 1st half until stalling at the 7 and settling for Hanson's field goal and a 13-3 score.
