D Darius Kasparaitis, discouraged by the slow movement of contract talks with the Penguins, plans to leave for Switzerland on Monday to train with Senators holdout Alexei Yashin.
Both players are represented by agent Mark Gandler.
Kasparaitis, recovering from reconstructive knee surgery, said he and the Penguins are about $300,000 apart in yearly salary, but that he has been making all the concessions. The Penguins' initial offer was $1.2 million a year.
"It's frustrating. It's killing me," Kasparaitis said. "I'm trying to keep my head up and I want to come back to Pittsburgh."
Penguins GM Craig Patrick suggested the team won't make a new offer any time soon.
"We've extended ourselves as far as we're going to extend ourselves," Patrick said. "I don't know if there is a line in the sand, but we've made a substantial offer, by our estimation. Obviously, not by theirs. And that's as far as we can go."
Kasparaitis, who has been working out on his own in New York, is the Penguins' last remaining restricted free agent who has not reached an agreement.
"You know, $300,000 isn't that big of a deal," Kasparaitis said, who isn't threatening to stage a long holdout. "But I'm the only one who keeps going down."
