Court-appointed attorney Kent Schaffer told the Associated Press on Monday that his client was injured in a fight on Thursday with another inmate at the Joe Corley Detention Facility in Conroe near Houston.
Schaffer says Stanford had "a concussion, two black eyes, a broken nose." Schaffer says Stanford was returned to the lockup Sunday afternoon.
Stanford is being held on charges of running a $7 billion Ponzi scheme. He has denied the allegations.
Stanford is charged with bilking investors of the now-defunct Stanford Financial Group. Schaffer says a status hearing is Oct. 14.
