The Penguins acquired Boucher from Dallas for defenceman Darryl Sydor on Nov. 16, but Boucher has been limited to two goals and two assists in 23 games with Pittsburgh. He has not played since Jan. 30.
Boucher's operation came on the same day defenceman Sergei Gonchar returned to the Penguins' lineup after being out all season with a dislocated left shoulder. Coach Michel Therrien said Gonchar would make his 2008-09 season debut in Toronto on Saturday night.
Gonchar is the only NHL defenceman to get at least 50 points in each of the previous eight seasons.
Penguins forward Ruslan Fedotenko, out since breaking his right hand in a fight with Atlanta's Colby Armstrong on Jan. 6, also was scheduled to play Saturday night.
It's cool when you think about how many great American players have played the game and the two players that were at that 18-game point streak and what they've done in their careers. It's pretty cool right now, but it was kind of overshadowed by the loss.
