A 60-second nightmare for Nagoya Grampus goalkeeper Seigo Narazaki dented his side's title aspirations and handed relegation-haunted JEF United Chiba a precious 2-1 win on Tuesday night.
With Grampus starting the second half at Fukuda Denshi Arena 1-0 up thanks to Yoshizumi Ogawa's 40th-minute goal, the Japan No. 1 bundled a Tatsuya Yazawa header into his own net before palming the ball into the path of Masaki Fukai for the second less than a minute later.
Oita Trinita beat Consadole Sapporo 3-2 earlier in the day to draw level at the top on points with Nagoya, with third- and fourth-place Urawa Reds and Kashima Antlers not in action.
