Alex Rodriguez went to a Miami gym this morning, after confessing to ESPN yesterday that he did in fact use performance-enhancing drugs. We don't yet know A-Roid's fate, but some of his sponsors could be dropping out.  One of his sponsors, Nike has released a statement saying, "Nike does not condone the use of illegal substances in sport and agrees with Alex Rodriguez that they should not be used," a rep for the company has said. "We will have no further comment at this time."
