Kawasaki Frontale defender Kyohei Noborizato could be out of action through September after tearing an abdominal muscle last week.
The 26-year-old suffered the injury during the team’s 2017 AFC Champions League quarter-final first-leg win against Urawa Reds.
Noborizato has 21 appearances, including 16 starts, for Frontale in their MEIJI YASUDA J1 League campaign.
