Winger Alexi Ponikarovsky, obtained by the Penguins late Tuesday night in a trade with Toronto, will not be able to join his new team until at least Friday because of an immigration holdup.

That means Ponikarovsky will miss Thursday's road game against the New York Rangers. His first possible game with the Penguins will be Saturday afternoon at home against Dallas.

Ponikarovsky -- who was dealt for prospect Luca Caputi and defenseman Martin Skoula -- does not have the proper work visa to be based in the United States. While with Toronto, he was able to play games in the United States as a visiting team member. He is Ukrainian.

Meanwhile, center Sidney Crosby is not practicing with the club. He is being given a rest after a long run in the Olympics followed by playing Tuesday night in a 3-2 home win over Buffalo.
