Stevie Young, who plays guitar for Australian rock band AC/DC, has left a Buenos Aires hospital, according to a Reuters witness.
Young was seen walking out of the clinic where he had been admitted the day before.
AC/DC, which is currently on an international tour, will perform in the Argentine capital next week and Young is expected to take part in the show, a spokesperson for the band had told Reuters on Thursday.
The band last played a show days earlier in Santiago and are scheduled to play in Mexico City by early April.
