Sergei Gonchar‘s departure from the Dallas Stars’ 3-2 shootout loss to the San Jose Sharks could leave them without another defenseman for an extended period.

Gonchar left the game in the second period with what was initially called an upper-body injury. Stars coach Lindy Ruff updated his situation after the game as Mike Heika of the Dallas Morning News shared.

“He’s all right,” said Ruff of Gonchar. “He took a puck to the face and isn’t feeling well, so he has to stay out for a while probably.”
