Closer Keith Foulke, who is also being brought along slowly after undergoing surgery on both knees last year, threw in the bullpen for the first time yesterday. Foulke was unavailable for comment. The team has refused to comment on reports that Foulke has been receiving injections in the knees this spring to provide lubrication in the joint due to the loss of cartilage. ?I?m not permitted to discuss it,? manager Terry Francona said. ?What is it, HIPPA? FEMA? Whatever it is, that?s the rules.
