Kashiwa Reysol midfielder Hidekazu Otani could potentially miss the remainder of the 2016 MEIJI YASUDA J1 League’s first stage after hurting his left knee.
The injury was sustained in Reysol’s midweek Nabisco Cup match against Albirex Niigata.
Otani, who has one goal in 11 appearances this season, is estimated to require six weeks to recover.
