Carolina Hurricanes forward Jiri Tlusty will miss two to three weeks after having his appendix removed.
The Hurricanes filled his spot by recalling forward Zach Boychuk from Charlotte of the AHL.
The moves were announced Friday, about nine hours before Carolina's game against the Eastern Conference-leading Pittsburgh Penguins.
The team says Tlusty underwent an emergency appendectomy on Tuesday.
This is the second time this season that Boychuk has been called up. He has eight goals and 13 assists in 86 career games with the Hurricanes, Penguins and Nashville.
