Two-time Masters winner Bubba Watson is the latest high-profile golfer to sign up with LIV Golf.
The American, 43, is currently recovering from a knee injury and will debut with the controversial Saudi-backed series in September.
The former world number two will be an off-course captain for the fourth event in the inaugural series in Boston.
Now ranked 86 in the world, Watson has 14 career wins but not played since the US PGA Championship in May..
