Pittsburgh forward Pascal Dupuis has been ruled out of the regular season and the playoffs while getting treatment for blood clots.
Dupuis, 35, hasn't played since beginning treatment for blood clots in November. The team initially held out hope Dupuis could return in time for the postseason. He is prohibited from contact while taking blood thinners to treat the condition.
General manager Jim Rutherford said he is "confident" Dupuis will be back in time for the 2015-16 season.
