All nine members of the Tufts University men’s lacrosse team who were hospitalized this month with the rare muscle injury rhabdomyolysis have been discharged, and the university says it has hired experts to investigate what led to so many serious injuries after a training session.

Tufts University says the members of the men's lacrosse team who were diagnosed with a dangerous medical condition following a Sept. 16 workout have been discharged from the hospital.

The university also said it has retained D. Rod Walters II and Randy Aliment of the law firm Lewis Brisbois to conduct an outside investigation into the workout.
