NHL-National Hockey League roundup

Feb 7 (The Sports Xchange) - The Pittsburgh Penguins announced Friday that defenseman Kris Letang will miss at least six weeks after suffering a stroke last week.

Further testing also revealed that Letang, 26, has a small hole in the wall of his heart that may have contributed to the stroke.

The condition is treatable with blood thinners and is not believed to be career threatening, the team said.

Letang has had the small hole in the wall of his heart since he was born.

He last played Jan. 27.

Letang was cleared by the team to go on vacation with his family during the NHL's Olympic break.

Letang has 18 points in 34 games this season.
