Bayern Munich says defender Daniel van Buyten has pulled out of Belgium's upcoming games with an Achilles' tendon problem.

The Bundesliga club said Tuesday it expects van Buyten back in Munich on Wednesday, when he will report to club doctors.

Belgium travels to Azerbaijan for a European championship qualifier on Friday, before a friendly with the United States four days later.

The 33-year-old van Buyten has played 62 times for his country, scoring nine goals.
