Miles Bergman has had a second operation on his right shoulder.

PORT ADELAIDE midfielder/defender Miles Bergman has had a second operation to stabilise his right shoulder after an issue arose with the initial surgery.

Bergman had a revision of the Laterjet procedure, after a routine check revealed a surgical screw from a previous off-season surgery had become loose.

The 20-year-old returned to training with his teammates at Alberton on Monday to continue preparations for season 2022.
