Falcao, who has netted 18 league goals this season, pulled up clutching his leg and had to be replaced in the 59th minute of the match at the Calderon, second-placed Atletico's 10th win in 10 home games this term.
Coach Diego Simeone said in a post-match news conference the player, who is coveted by several of Europe's richest clubs, could be sidelined for around three weeks.
