For what it's worth, Meredith Marakovits notes that Vidal Nuno is listed on the roster as a starting pitcher now. As I mentioned yesterday, Nuno is the only pitcher on the Yankees' roster that's stretched out enough to start for a reasonable number of innings. The plan is likely to start him against the Angels, and then switch him with David Phelps to gain the platoon advantage. As Phelps builds up his pitch count, the Yankees will probably make the real decision on who becomes the regular starter. I also expect to see Manny Banuelos bumped to Scranton or Trenton soon. Anyway, here's tonight's lineup against the Red Sox.
Edit: (4:12 PM) The Yankees have also announced that additional tests of Ivan Nova's elbow show that he has indeed torn his UCL. The team's doctor has recommended surgery (Tommy John), and I'd imagine that he schedules that as soon as possible. The recovery time is usually 12+ months, so he could be back as soon as next year, but the Yankees are usually very cautious.
Edit: (5:14 PM) Joe Girardi confirmed that Nuno will start Saturday against the Angels.
