Celtic defender Mikael Lustig controls the ball during the Scottish League Cup semi-final against Rangers . It ’ s the latest frustration for Lustig in a long line of injury setbacks which have included hip , groin and thigh injuries . He missed a large part of last season too after being forced to undergo hip surgery . ‘ I have to put this season to one side , ’ Lustig said . ‘ I have been out for six weeks now and the foot is still swollen . I have a stretched ligament on the inside of my foot and bruised the bone on the outside . Lustig ( second right ) and John Giudetti ( right ) celebrate Celtic 's win against Rangers last month . ‘ It may take three months before I ’ m good again . ‘ But I have to look on the positive side because I don ’ t require an operation . ‘ We will see how long it takes , but it ’ s looks like the season is over. ’ Injury-prone Lustig has managed just 36 starts for Celtic since signing from Rosenborg in 2012 .
