Penguins' Kris Letang out 4 to 6 months with herniated disc

Pittsburgh Penguins defenceman Kris Letang's season is officially over.

Letang will undergo surgery for a herniated disc in his neck and will be out between four and six months, the team announced Wednesday.

"Kris underwent an MRI in February that revealed a herniated disc in his neck," general manager Jim Rutherford said. "Our neurosurgeons examined him and recommended conservative treatment in an attempt to correct the condition without surgery.

"Kris had been making progress and was hopeful of returning for the playoffs until about a week ago, when the progress plateaued. He underwent another MRI, and, at that point it was determined that surgery was needed."

The Montreal native has missed the team's last 20 games and has not played since Feb. 21.

Letang has scored five goals and 29 assists for 34 points in 41 games this season.
