Defender Oh Jae-Suk has temporarily left Japan in order to renew his South Korean passport, club Gamba Osaka revealed on Thursday.

The 25-year-old will rejoin his teammates in approximately 10 days, and is unlikely to be at coach Kenta Hasegawa’s disposal for the must-win game against Vegalta Sendai next Saturday.

Oh, who was part of South Korea’s bronze-winning side at the 2012 London Olympics, has made just three league appearances for Gamba this season after enduring bad luck with injuries.

Anything less than all three points at home to Vegalta next will allow 2015 MEIJI YASUDA J1 League front-runners Urawa Reds to clinch the first stage title.
