Norichika Aoki (YAK) is scheduled to have his tonsils removed later this month. Seems he'll also have what sounds like a laser submucosal resection (to treat allergies) and corrective surgery on his nasal bone.
Said Aoki, "My tonsils would flair up and then I'd get a fever or a headache. My nose was stuffy a lot, making me breath through my mouth instead of my nose. And that caused the tonsil flair ups. I'll be taking care of all of that so I can focus more on playing.
