John Goodman has checked out of rehab after being treated for an undisclosed reason. It was unclear how long the actor was treated, or when he was released.

"For my family and myself, I voluntarily took the necessary steps to remain sober the rest of my life," Goodman said in a statement issued by his publicist, Stan Rosenfield.

Goodman left Promises Treatment Center in Malibu, "Entertainment Tonight" reported Wednesday on its Web site.

Reached by e-mail late Wednesday, Rosenfield referred to the statement and declined further comment.

Goodman, 55, is best known for playing Dan Conner on the hit sitcom "Roseanne" in the 1980s and '90s. His film credits include "The Big Lebowski," "The Flintstones" and "The Babe."

He won an Emmy Award this year for guest actor in a drama series for "Studio 60 on the Sunset Strip."
