World No. 3 Vijay Singh is expected to be sidelined for at least two months because of an arm injury.

Tendinitis in Singh’s left forearm has ruled him out of the Iskandar Johor Open in Malaysia from Oct. 30-Nov. 2 and the Champions Tournament in Shanghai from Nov. 6-9.

“I am very disappointed to miss the Iskandar Johor Open and the HSBC event as I was looking forward to returning to Asia,” the 45-year-old Singh said in a news release issued by the Asian Tour on Tuesday.

“As disappointing as it will be to miss the tournaments it is important I follow my doctor’s instructions and do what is best for my long-term health.”
