Kashima Antlers crashed Gamba Osaka's house party with a 1-0 victory in the J. League on Sunday, 19-year-old Yuma Suzuki coming off the bench to score the lone goal midway through the second half.
Including Gamba, eight of the nine clubs at home lost on the opening weekend of J1. Sagan Tosu, who beat Avispa Fukuoka 2-1 on Saturday, were the only team to avoid embarrassment.
Sunday's defeat cost Gamba three points and Japan defender Daiki Niwa, who broke his collarbone in the first half. No timetable was set for his return, although it appears certain he will miss next month's World Cup qualifiers at home to Syria and Afghanistan.
