Barcelona confirmed on Monday that defender Thomas Vermaelen has been ruled out of action for four weeks with a calf injury picked up against Levante.
"The first team player Thomas Vermaelen felt a problem in Sunday's game away at Levante. Tests carried out on the defender show that he has a torn muscle in his right calf and will be out for around 4 weeks," the club said in a statement on their official website.
The Belgium international started Sunday's 5-0 La Liga win over Levante. However, he was replaced by Arthur on 52 minutes at the Estadio Ciudad de Valencia.
