text: David Luiz could be a doubt for Paris Saint-Germain's Champions League clash with Barcelona after picking up a hamstring injury on Sunday. The Brazilian defender went off after 35 minutes of PSG's 3-2 win over Marseille after suffering an injjury to his left leg. Shortly after his side had fallen behind in their top of the table clash,the Brazilian was running away from a Marseille player, before being caught by a stray leg. David Luiz carries the ball out of defence on one of his trademark forays, but one such run led to his injury . The Brazilian defender immediately signalled to the bench that he would need to be replaced . The former-Chelsea defender attempted to continue breaking forward, but pulled up sharply holding his hamstring a couple of yards later. The club's official English Twitter account confirmed it was a muscle pull, tweeting: '@DavidLuiz_4 crumples to the floor with a hamstring pull #OMPSG' Reports suggest the 27-year-old will have scans on Monday to assess the extent of the injury. If it is serious as suggested then Luiz will surely be a doubt for PSG's upcoming games with Saint-Etienne, Bastia and Barcelona, whom the French side face in the first leg of their Champions League quarter-final on April 15. in his absence the French champions looked less than assured, conceding a second poor goal just a few minutes after Luiz departed, but they rallied to win the game and return to the top of the table with a better second-half display. Luiz limped off, and could now be a doubt for the Champions league quarter-final against Barcelona . PSG will hope their star defender can recover quickly, as he is a key part of their plans .
