Juventus's Chiellini out for 20 days with torn muscle

(Reuters) - Juventus defender Giorgio Chiellini is expected to be out for around 20 days with a torn muscle in his right leg, the Serie A club said on Tuesday. Chiellini joins an injury list that already includes midfielder Sami Khedira and defender Martin Caceres (nL8N15K2FO) and will miss Saturday's top-of-the-table clash with leaders Napoli. A 20-day absence would rule the Italy international out of the first leg of Juventus's Champions League last 16 clash with Bayern Munich on Feb. 23.
