The newly named conductor of the Boston Symphony Orchestra Andris Nelsons was forced to withdraw from the orchestra's July 27 performance at Tanglewood after suffering a severe concussion, according to a statement from the BSO's managing director Mark Volpe. 

Nelsons was to be the featured conductor for Verdi Requiem on July 27 at the summer home for the BSO. It would have been his first performance with the orchestra since he was named music director of the BSO in June. 

He was struck in the head by a door that "unexpectedly swung open" at his home in Germany, according to Volpe. Doctors advised him to take time out of his schedule and not travel by plane. 

"Truly, I feel a great sense of sadness at not being able to come to Tanglewood this week to conduct the Verdi Requiem," Nelsons said in a statement. "I will miss you all and am very sorry indeed that this very unfortunate accident prevents me from being there."

Nelsons' next scheduled performance with the orchestra is in October in Boston.
