Matt Diaz was fit for a new cast Thursday and will be examined again by hand specialist Dr. Gary Lourie on Monday. Diaz would like to avoid season-ending surgery on the thumb, but it's possible that might end up being the course of action. He received a second opinion on the thumb recently from Dr. Thomas Graham in Cleveland. "He agreed with his assessment in the fact that if it doesn't calm down on its own there's no sense in waiting around months to go ahead and get (surgery)," Diaz said. "We should know something in the next week."
