Milwaukee Bucks forward Charlie Villanueva is scheduled to have surgery on his right shoulder next week.

The team made the announcement Thursday, one day after officials determined Villanueva would miss the final few weeks of the season because of nagging tendinitis in his shoulder. Bucks center Andrew Bogut also will miss the rest of the season because of a sprained left foot.

"It's more exploratory," general manager Larry Harris said Wednesday. "It could be a short amount of time. It could be a longer amount of time."
