L.A. Kings Insider reports Quick "underwent a 'minor surgical procedure' today to repair a disc fragment and an inflammatory cyst that had formed in his back."
It said Quick would begin rehabilitation in a week.
Assistant general manager Ron Hextall told the website the team was aware of Quick's condition earlier in the summer but tried a solution of therapy prior to choosing surgery.
According to the website, "Hextall said the recovery, through therapy, 'wasn't coming along quite like we hoped, so the next step was to go this route.'
"Hextall said Quick should be ready for full activity 'sometime around' the scheduled start of training camp, but noted that every player's recovery time is different."
Quick was awarded the Conn Smythe Trophy after the Kings won their first Stanley Cup this postseason. He was nominated for the Vezina Trophy after a regular season when he was 35-21-13 with a 1.95 goals-against average, .929 save percentage, and 10 shutouts.
He signed a 10-year contract extension worth $58 million, according to Capgeek.com, in June.
