It's an annual tradition after the postseason to learn what injuries players were fighting through in their quest for the Cup. You can add Jonathan Quick to the list for 2013-14.
The LA Kings goalie, who started every game on the Kings' postseason run that culminated with the Stanley Cup, was dealing with a hand injury that required surgery on Tuesday. Specifically he was suffering from a wrist injury.
Quick's surgery was confirmed by a Kings spokesman to Yahoo Sports and is scheduled to keep him out of action for 10-12 weeks. Obviously that's over the course of the offseason so Quick won't miss any time but it could have him behind schedule for next season as the injury will require him to stay off the ice.
As to when Quick suffered the injury, it came way back in the second round of the playoffs against the Anaheim Ducks. That's a long time for a goalie to play with a wrist injury -- the Kings played the Blackhawks and Rangers afterward -- no matter which wrist is injured (that hasn't been specified).
It didn't seem to hamper Quick all that much, especially in the Final. With a strong Final he brought his save percentage up to .911 in the postseason, certainly lower than what we've seen from him in the past but obviously good enough.
