Smith became the first player in NFL history to reach 11 consecutive 1,000-yard seasons, surpassing a record of 10 he shared with Sanders, in the Dallas Cowboys' season finale Sunday against the Lions.
Needing 56 yards to reach 1,0000, Smith rushed for 45 by halftime. With 3:54 left in the third quarter, Smith took a pitch left and ran behind Pro Bowl guard Larry Allen for a 13-yard gain to pass 1,000 yards.
It appeared Smith would fall short of the feat, but he rushed for a total of 254 yards over the last two weeks in games against Arizona and San Francisco.
Smith surpassed Sanders and moved into second place on the all-time rushing list on September 23.
In his 12th season with the Cowboys, the 32-year-old Smith entered Sunday with 16,110 yards. Sanders rushed for 15,269 yards in 10 years with the Detroit Lions.
