Geelong Category B Rookie Stefan Okunbor suffered a ruptured Achilles tendon at training on Wednesday.

After consultation with a specialist, the 21-year-old Irishman will have the injury surgically repaired on Sunday.

The former Gaelic footballer joined the Cats at the end of 2018 and played eight VFL games in 2019.

The club will work closely with Okunbor on his rehabilitation plan over the coming weeks.
