BOSTON — The incoming director of the Boston Symphony Orchestra has canceled a weekend appearance at Tanglewood after suffering a concussion following a freak accident in Germany.

Mark Volpe, the orchestra’s managing director, said this week that Andris Nelsons collided with a door that unexpectedly swung open at his residence in Bayreuth, Germany.

Nelsons was hospitalized and doctors advised him against airplane travel. He’d been scheduled to conduct the Verdi Requiem on Saturday at Tanglewood, the BSO’s summer home in Lenox.

In a statement, Nelsons said he felt “a great sense of sadness” at missing the concert but that he looked forward to performing with the BSO in Boston in October.

Health problems forced Nelsons’ predecessor, James Levine, to resign. Nelson is much younger and is known for his physical vitality.
