The team said Seguin had the procedure Tuesday and was expected to make a full recovery in four months.
The 25-year-old Seguin led the Stars in scoring with 72 points (26 goals, 46 assists) in a disappointing season. Dallas missed the playoffs a year after being the top seed in the Western Conference and winning a first-round series against Minnesota.
The Stars didn't renew coach Lindy Ruff's contract and hired Ken Hitchcock, the coach for the franchise's only Stanley Cup title in 1999.
