Frank Gore ran his way to another career milestone and then was forced to watch the New York Jets’ second win from the sideline.

The 37-year-old running back became the third player in NFL history to run for 16,000 yards, joining Pro Football Hall of Famers Emmitt Smith (18,355) and Walter Payton (16,726). But his 4-yard carry in the fourth quarter to put him at exactly 16,000 was his last of the day Sunday because of a chest injury.

Coach Adam Gase had no immediate update on Gore, who finished with 14 carries for 48 yards. It’s uncertain if Gore will be able to play in the season finale next Sunday at New England in what could be the last game of his NFL career.
