Oita Trinita on Tuesday announced that striker Ryo Nagai will require eight weeks to recover from an injury to his right knee.
The Cerezo Osaka-loanee suffered damage to his medial cruciate ligament on 17th May against MEIJI YASUDA J2 League opponents Mito Hollyhock.
Nagai, who at this time will not require surgery, has scored two goals in nine appearances this season.
