Andres Iniesta hobbled off in the first half of Barcelona's top-of-the-table clash against Atletico Madrid on Sunday. The midfielder pulled up and appeared to have strained his hamstring at the Nou Camp - an injury later confirmed by the club. He played on but was eventually replaced by Andres Gomes as Barcelona looked to extend their lead at the top of the league. Iniesta will undergo tests this week to determine the extent of the injury but looks to miss the trip to Malaga next weekend and the visit of Chelsea five days later.
