Ahmed Zayat said Tuesday morning that Kentucky Derby runner up Nehro will not go in Saturday’s Preakness.  “He couldn’t look any better. His work on Monday was absolutely awesome. I’m just concerned about him having four hard races in eight weeks, even if, outwardly, he doesn’t appear to be showing it.” Up next: The Belmont.
