Amon-Ra St. Brown had six catches for 71 yards and a score, and Lions rookie Brian Branch returned Patrick Mahomes' first pick in an opener 50 yards for another touchdown as Detroit snapped the Chiefs' eight-game Week 1 winning streak.
The Lions were trying to run out the clock when Goff had a fourth-down pass near midfield batted down with 2:30 left, giving the Chiefs a chance.
When it fell incomplete and Detroit took over, Montgomery ran for a first down that allowed the Lions to run out the clock.
Mahomes finished with 226 yards passing and two touchdowns, despite his receivers dripping a slew of passes.
He also was the leading rusher for the Chiefs, whose self-inflicted wounds proved too much to overcome.
