MADRID: Barcelona's French defender Lilian Thuram has been ruled out of action for six weeks after tearing a muscle in his left leg.   
 
Thuram suffered the injury in the action that saw Atletico Madrid's Sergio Aguero score the equaliser in a 1-1 Premira Liga draw at the Nou Camp Thursday.   
 
The 35-year-old former World Cup winner is expected to be back in action at the beginning of February.
