Dallas Stars defenseman Sergei Gonchar will miss the next seven-to-10 days with concussion-like symptoms, general manager Jim Nill told Stars beat reporters Sunday.

Nill is hoping Gonchar will be back after the Christmas break and said there won't be a call-up from the Texas Stars of the American Hockey League.

Gonchar left the Stars' game Saturday against the San Jose Sharks in the second period with what was initially called an upper-body injury.
