The 24-year-old went off injured towards the end of Connacht’s Guinness PRO12 defeat to Edinburgh at the Sportsground on Friday.
After an MRI and consultation with an orthopaedic surgeon, it was revealed that the former Counties Manukau and Chiefs man had sustained a ruptured syndesmosis.
Aki will have surgery next week and is expected to be out for eight to 10 weeks.
