ARLINGTON, Texas — Joba Chamberlain has been placed on the 15-day disabled list by the New York Yankees, who have not yet revealed the extent of his injured pitching shoulder.

Yankees manager Joe Girardi said before tonight's game against Texas that he had no updates regarding Chamberlain's examination by noted orthopedic surgeon Dr. James Andrews in Alabama.

Chamberlain was sent to see Andrews after undergoing an MRI on his ailing right shoulder yesterday. The 22-year-old right-hander was removed from Monday night's start against the Rangers in the fifth inning with stiffness in his shoulder.
