Before signing with the Flyers two years ago, Chris Pronger had a typical injury history for a 34-year-old NHL defenseman.

In addition to surgeries on each of his knees and his left wrist, he suffered a broken left foot, a broken toe, a separated shoulder and a broken jaw over the span of 15 NHL seasons.

Not bad for a guy who makes a living blocking shots.

But in the past 10 months Pronger has undergone reconstructive surgery on his right knee, a surgery to stabilize a fracture in his right foot and a surgery to have a plate inserted in his fractured right hand.

Today, Pronger will have a herniated disc removed from his lower spine at The Hospital for Special Surgery in New York. According to Flyers general manager Paul Holmgren, back specialist Frank Cammisa will perform the procedure.

Pronger's back started giving him problems in Game 7 of the Flyers' first-round playoff series against the Buffalo Sabres and the pain continued in Game 1 of the Flyers' second-round series against the Boston Bruins. When Pronger reported a loss of strength in his legs he was pulled from the lineup.

Pronger sat out the final three games of the Bruins' four-game sweep and spent the early part of this week visiting with back specialists. On Wednesday it was decided he would undergo what is called a discectomy. Flyers goaltender Michael Leighton underwent a partial discectomy on Oct. 11 and returned to action six weeks later.

However, several months after the surgery, Leighton said he experienced numbness in his legs and on Wednesday he underwent hip surgery to repair a torn labrum.
