Torino winger Mario Santana could spend a month on the sidelines after suffering a leg injury. The on-loan Fiorentina player had to be withdrawn after nine minutes of Il Toro\'s 1-1 draw at Genoa and medical tests have now identified muscle damage as the problem. A statement on torinofc.it read: \"The Argentinian winger has undergone an ultrasound scan which revealed a first-grade lesion to the long adductor muscle of his left thigh. Santana will undergo a further ultrasound scan on December 27. The estimated period of his absence is currently one month.\" The 30-year-old has made 14 appearances in Serie A, scoring one goal, since moving to the Stadio Olimpico on a season-long loan. Santana will miss Torino\'s home game with Chievo on Saturday before a two-week winter break begins. From FIFA
