Calling this year the "toughest" of his career, Pronger said on a conference call with reporters: "The year from hell is over. I started the season with a surgery and I'm going to end it probably, who knows, whether I get another one or not."
Flyers general manager Paul Holmgren told CSNPhilly.com that Pronger has either a bulging or herniated disk and it is uncertain if he will need back surgery. The report said his status will be updated later in the week.
Pronger said he did not know when the injury occurred, but he started to feel pain in Game 7 of the first round against the Buffalo Sabres.
The defenseman added that his surgically repaired hand was not 100 percent but was healed enough for him to play, according to NHL.com.
Pronger had surgery on his right knee in August, his right foot in January and his right hand in March. He played only 50 regular-season games and limited time in three postseason games.
