It appears that David Luiz has taken the phrase 'twiddling my hair' literally judging by the injured Paris Saint-Germain star's latest Instagram post. The PSG defender is out for at least four weeks after scans revealed that the 27-year-old suffered a torn hamstring in Sunday's 3-2 win at Ligue 1 title rivals Marseille. And it seems that boredom has already kicked into the usually jovial Brazilian as he sported a new hairdo on Wednesday. David Luiz posted an Instagram picture sporting a new hairdo in the style of a man bun on Wednesday . Luiz (centre) has time on his hands at present after tearing a hamstring at Marseille on Sunday night . The Paris Saint-Germain defender immediately signalled to the bench that he would need to be replaced . Accompanied with the caption: 'Parisien!' Luiz has his usually flowing brown locks styled into a man bun. The centre back's new look seems to be a source of amusement for his PSG team-mate Lucas Moura who later shared a picture with Luiz among his Instagram followers. 'I'll let you choose the nickname,' the midfielder wrote as he referred to Luiz's barnet later that afternoon. And while Luiz's hair may be a laughing matter to his team-mates, his injury will not be for manager Laurent Blanc as they seek Ligue 1 and Champions League glory this season. The former Chelsea defender will miss both legs of their quarter-final tie against Barcelona in Europe, while potentially missing eight league matches as they look to defend their crown.
