The 49ers ended their streak of 26 quarters spanning six straight regular-season games without a turnover, and 36 consecutive quarters without a lost fumble since Davis lost one Nov. 6 last year at Washington. San Francisco was trying to match the 2010 Patriots for the NFL record of seven games without a turnover.

After Hanson’s first field goal, Kendall Hunter fumbled the kickoff return after being stripped by Tahir Whitehead and Kassim Osgood recovered. It marked the first career lost fumble in 18 games for the second-year halfback.

But Ahmad Brooks batted down a pass on third down in the ensuing series as the Lions had to settle for another field goal.

San Francisco’s defense delivered again on Detroit’s next series. On third-and-6 from the 20, Stafford threw down the middle of the field with nobody even close and safety Dashon Goldson jumped in for an interception.

‘‘We know what our defense is going to give us,’’ Gore said. ‘‘We need to match them.’’

Notes: Gore needs one rush next week at Minnesota to pass friend and mentor Roger Craig (1,686) for most attempts in franchise history. ... Stafford also failed to become the first player in NFL history to pass for 2,000 yards in a five-game span. ... Crabtree wound up with six catches and Davis five as Smith completed passes to seven receivers.
