The Penguins, who have won 14 consecutive games, acquired Iginla from the Calgary Flames on Thursday but he is not permitted to work in the United States because he is a Canadian citizen.
The immigration issue could be delayed until next week because government offices in Canada are closed for Easter on Sunday and also are closed Easter Monday, which is a national holiday in Canada.
From the Pittsburgh Tribune-Review:
The Penguins would prefer Iginla be able to practice with them once before participating in a game. He has played his entire 16-season career in Calgary, and the Penguins hope to at least briefly introduce him to their system in a non-game environment. Following Saturday's game against the Islanders, the Penguins have a scheduled off day on Sunday before practicing again Monday. They host the Buffalo Sabres on Tuesday, which could mark Iginla's debut.
