(CNN) -- World number two Phil Mickelson has confirmed he will not take part in the British Open, which begins in Turnberry on Thursday.
Mickelson's decision to miss the British Open at Turnberry next week is not a surprise.
The American, who has been replaced by compatriot Ben Crane in the 156-player field, has pulled out so he can be with his wife and mother who are both battling cancer.
Mickelson, who has contested every Open since he turned professional in 1994 but only finished in the top 10 once when he was third at Troon in 2004, confirmed his decision with an announcement on his official Web site, www.philmickelson.com.
He said: "As a professional golfer, competing in major championships, and winning them, is my main objective.
"But I've always said family is my number one priority. For that reason I won't be playing the British Open at Turnberry next week.
"It's a trying time for us as we await more test results but we have excellent medical attention and care, we've received wonderful support from so many people, many of whom have gone through the same battle, and we're optimistic, as always."
