Andres Iniesta is a doubt for Barcelona's return Champions League match with Chelsea after suffering a hamstring injury in Sunday's La Liga match with Atletico Madrid.
The 33-year-old midfielder limped off after 36 minutes at the Nou Camp having suffered the problem around the 22-minute mark.
Barcelona confirmed the hamstring injury and said Iniesta will undergo tests to ascertain how long he will be sidelined.
However, he must surely be doubtful for the second leg of the last-16 tie against Chelsea at the Nou Camp on March 14, with the scores tied at 1-1 following the first match.
