The San Jose Sharks' disappointing season just took another hit with news that forward Tomas Hertl is done for the season after suffering a knee injury Wednesday.

The team announced that he suffered a torn ACL and MCL.

Toronto Maple Leafs forward Auston Matthews (wrist) won't play in this weekend's NHL All-Star Game, but he will attend the event in St. Louis, the team announced Wednesday. Matthews, 22, is day-to-day while he gets treatment for an ongoing wrist issue, Toronto said.

If the Sharks are going to turn their season around, it won't involve Logan Couture for several weeks.

Couture is expected to miss up to six weeks with a fractured ankle that he suffered Tuesday night in the Sharks' 3-2 loss at the Blues, GM Doug Wilson confirmed Thursday. Couture was in a walking boot after Tuesday's game. He awkwardly slammed his left leg into the end boards in the second period.
