Luis Suarez's four-month biting ban has been upheld by the Court of Arbitration for Sport, but the Uruguay striker can now train with new club Barcelona. A full explanation of the ruling will not be published until a later date. Suarez's lawyers argued world governing body Fifa's decision to suspend him from all "football-related activity" for biting Italy's Giorgio Chiellini at the World Cup was excessive. Suarez, 27, will be available from the match at Real Madrid on 26 October. He will also continue to serve his nine-match international ban but, having previously been banned from all "football-related activity", the former Liverpool player can now train and attend matches as well as undertake promotional activities.
