Riccardo Muti To Have Surgery

Chicago Symphony Orchestra music director Riccardo Muti will undergo surgery today to repair the "multiple facial and jaw fractures" he sustained after collapsing at Thursday's CSO rehearsal, said orchestra president Deborah Rutter. Additionally, medical staff at Northwestern Memorial Hospital is continuing tests in an attempt to determine the underlying cause of the spell, Rutter said in a statement released by the orchestra Friday.

Muti - music director of the Philadelphia Orchestra in the 1980s before fading from the scene in the early 1990s - will miss at least two weeks of concerts in Chicago. Muti canceled his previous Chicago appearance, in October, after complaining of stomach pains.

We wish both Muti and the orchestra the best possible outcome.
