The surgery, which consists of moving the upper jaw and the lower jaw forward, is aimed to relieve his lingering sleep apnea. Napoli also dealt with injuries to his finger, toe, and back this season, but he will not require surgery for any of them."
Now, I have sleep apnea, but "moving the upper jaw and lower jaw forward" sounds painful and a little confusing. Isn't another word for "upper jaw" the "skull"?
We like projections, so Mike Napoli before having his upper and lower jaw extended forward...

And projected Mike Napoli after...

Not much different....
