Minnesota United denied reports that James Rodriguez was suffering from a potentially fatal health condition on Monday as the Colombian star returned to training after being sidelined for several days due to severe dehydration.
Rodriguez, 34, was hospitalized for three days with dehydration last week after being taken ill during Colombia's 3-1 loss to France on March 29 in Landover outside Washington.
Some US media initially reported that the Colombia captain was suffering from rhabdomyolysis – a severe breakdown of muscle tissue that, in extreme cases, can be fatal.
"Minnesota United FC takes the health and privacy of its players seriously," the Major League Soccer side said in a statement.
"The club and our medical professionals can unequivocally state there has been no clinical or laboratory evidence of rhabdomyolysis."
Minnesota said Rodriguez had been recovering at home after being discharged last week before returning to training on Monday, where he participated in "a supervised return-to-activity" session.
"His reintegration into full team training will follow the protocols established by the club's medical department and will be guided entirely by his clinical progress," Minnesota said.
