Nigeria international Godfrey Oboabona , 24, faces a lengthy spell on the sidelines with a knee problem.

Rizespor have revealed that the central defender underwent an operation at Sports Athlete Acibadem Health Center in Fulya following a meniscus injury.

Tests conducted before the Super Eagles star went under the knife suggest that there was also damage to the cartilage.

Rizespor have refused to disclose the date the central defender is expected to return to full training.

This season, Oboabona has suited up 8 times in the Super Lig, netting once.
