Hudson expected for spring training
The surgery on Monday was performed by Dr. Stevan Wray in Atlanta.
The Braves say Hudson has had discomfort in his back the past two seasons. The surgery was scheduled after the pain became worse during his offseason workouts.
Braves general manager Frank Wren said ''the prognosis is positive'' for Hudson to pitch in spring training.
The 36-year-old Hudson was 16-10 with a 3.22 ERA for the Braves this year.
