Yankees general manager Brian Cashman said that Mark Teixeira felt a "pop" in his right wrist and will be shut down for at least two weeks. Cashman added that he is "very concerned" about the first baseman. The Yankees' initial diagnosis was a strained wrist, but Teixeira is headed back to New York for more tests, and it sounds like the injury could be fairly serious. An update on his status should be available before the end of the week.
