Defenceman Randy Jones will be lost to the Philadelphia Flyers for between three to four months, according to the club.
General manager Paul Holmgren told the media of the severity of the injury following the team's loss to the New York Rangers on Saturday night.
Jones, 27, underwent surgery to repair a torn labrum in his right hip. The new timeline is roughly double the length of what the team estimated earlier in the week, before the surgery was performed.
The defender told reporters last week the hip ailment had been developing over time and wasn't related to one specific incident.
Jones has scored nine goals and 52 assists in 170 career NHL games, all with Philadelphia. The Quispamsis, N.B., native played collegiately at Clarkson University and was undrafted upon turning pro.
