Barcelona defender Gerard Pique will be out for two weeks after picking up a calf injury in his side's 3-1 defeat to Real Sociedad on Saturday, the club confirmed on Sunday. Pique endured a rare torrid evening in San Sebastian as a third league defeat of the season left Barça three points adrift of Real Madrid at the top of Spanish La Liga. The Spanish international could be back in time for the second leg of Barca's UEFA Champions League last 16 tie against Manchester City on 12 March. However, he is likely to miss Spain's final friendly before Vicente del Bosque names his squad for the FIFA World Cup™ against Italy on 5 March, as well as La Liga matches against Almeria and Valladolid.
