The Sharks have said only that Couture has an upper-body injury.
Sharks general manager Doug Wilson said no specific return date has been set.
Couture has 14 goals and 21 assists in 43 games this season. After going 11 straight games without a goal, Couture recently scored in four straight. That streak was snapped Sunday in Chicago, but he still had an assist and the shootout winner.
It's pretty crazy, but believe me when I say we didn't draft these players with the mindset we had to because they had good hockey-playing dads. It just turned out that way. But we're certainly glad they're a part of our organization.
