PORT ADELAIDE forward Charlie Dixon has had minor surgery on his ankle to clean out some troublesome scar tissue.

Dixon was close to returning to the field following earlier ankle surgery before reporting soreness on the inside of his ankle after an incident in training last week.

Follow-up imaging showed the 31-year-old developed some early bone bruising, likely due to some scar tissue build up, which was subsequently cleaned out on Wednesday.

Dixon is now recovering from the procedure and expected to be back training in a month.
