I ain't even mad, but it always surprises me that they don't know about these injuries right when the season ends and take care of it ASAP.
Invasive surgery isn't always the way to go. As written in the article - Quick and the Kings had been aware of the back issue since the start of summer, but that therapy, and not a surgical procedure, had initially been recommended. It just wasn't coming along quite as quick as they'd hoped, so now they opted for the Surgery at a time that should still allow him to be ready around camp-time. Assuming there is a camp on time, of course.
