Sulzer was acquired from Vancouver on Feb. 27 in the deal that also brought Cody Hodgson to Buffalo.
"(Sulzer) played very well with Christian (Ehrhoff). And I think the other thing you really notice out there is his composure; his ability to not only break up plays defensively, but to make plays offensively with the patience that he showed," said Sabres GM Darcy Regier. "We were pleasantly surprised with his play, and that moved us toward getting him signed."
In 89 career NHL games, Sulzer has amassed 16 points (4 goals, 12 assists), while playing with Buffalo, Vancouver, Florida and Nashville. The Kaufbeuren, Germany native was drafted in the third round (92nd overall) of the 2003 NHL Entry Draft by the Predators.
