Sasuke's sword was impaled in Naruto, and due to his weakened ocular powers he was unable to use Susano'o. What would he have deflected Shin's blades with? As for why he didn't tell Naruto, IDK but the beginning of the fight clearly shows a close up of Shin's seal followed by Sasuke having an exclamation point above his head.
