Sharks' Couture helped off ice after hard hit into boards

San Jose Sharks captain Logan Couture had to be helped to the dressing room after he was hit awkwardly into the boards by St. Louis Blues defenseman Vince Dunn during Tuesday night's game.

Couture was seen clutching his left knee as he left the ice.

The Sharks later announced Couture was being evaluated and would not return to the game.

Interim head coach Bob Boughner said postgame he "believes" the X-rays were negative and doesn't think Couture's injury is "too, too serious."

A significant injury to Couture would mark the latest setback in what's been a disastrous season in the Bay Area. The Sharks entered Tuesday's action eight points out of a playoff spot, but Couture has been a lone bright spot, leading the team with 36 points.
