Phil Mickelson has had surgery for a sports hernia for the second time in three months and is not sure when he will play next.
Mickelson first had surgery on his hernia in October, after playing in the Safeway Open. His management company said on Monday the five-time major champion was expected to make a full recovery, but did not offer a timetable for his return.
Mickelson had planned to start 2017 at the CareerBuilder Challenge from January 19-22 in Palm Desert, California.
The statement said the 46-year-old was looking forward to the tournament, at least in his new role as ambassador for the event.
Mickelson hasn't won a title since the 2013 British Open.
