In December 2008, it was announced that Ljungberg would undergo surgery to repair a persistent hip injury that has plagued him throughout his later career. Surgeons repaired a slightly torn hip labrum and shaved a small amount of bone where the hip meets the femur to prevent future injury. "The Seattle Times" reported that Ljungberg was expected to miss ten to twelve weeks of training and possibly be sidelined for the team's inaugural game, but he recovered from his hip injury sooner than expected. Although Ljungberg did not take part of Seattle's preseason in Argentina, he did however do light training with IS Halmia.
