KANSAS CITY: Jared Goff threw for 253 yards and a touchdown, new Lions running back David Montgomery ran for the go-ahead score with 5:05 remaining in the game, and Detroit held on for a sloppy 21-20 victory over the Super Bowl champion Kansas City Chiefs in the NFL's season opener Thursday (Friday in Manila).

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, helping Detroit snap the Chiefs' eight-game Week 1 winning streak.
