Alexander Noren of Sweden has withdrawn from the British Open at St. Andrews.

The R&A did not disclose why Noren, who celebrated his 33rd birthday on Sunday, had to withdraw. He was replaced in the field by Hiroshi Iwata of Japan.

Noren, who qualified from the current Race to Dubai standings on the European Tour, is the third player to withdraw in the last five days. Defending champion Rory McIlroy took himself out of the Open because of an ankle injury from playing soccer. Chris Kirk withdrew Saturday because of a hand injury.

The Open begins on Thursday.
