Paul Casey has become the latest player to join the Saudi-backed LIV Golf Invitational Series, despite previously having said he would be a "hypocrite" to play in the Saudi International.
The 44-year-old is scheduled to compete in the third LIV Golf event at Trump National Golf Club Bedminster later this month, although he has not played since March due to a back injury.
Casey, who is a former UNICEF ambassador, opted out of the inaugural Saudi International on the European Tour in 2019, citing concerns over the country's human rights record.
In an interview with The Independent in March that year, he said: "It just didn't sit well with me.
"I've not talked too much about it and I'm not sure I want to, but certainly signing a deal and being paid to be down there, I would be a hypocrite if I did that."
However, he subsequently performed a U-turn and has played the Saudi International – now part of the Asian Tour – in each of the last two years, outlining his reasons to the PA news agency in November 2020.

"This is not a decision I've taken lightly," Casey said. "I wasn't comfortable going in the past, but I have always been open-minded and willing to learn.
"I believe sport has the power to affect change. I've listened to the Saudis' commitment to this and their vision for the future.
"It is always better to include rather than exclude when eliciting change, thus I hope my participation will make a difference and I am looking forward to seeing these changes in person."
Casey will join former Ryder Cup teammates Lee Westwood, Sergio Garcia, Ian Poulter and Graeme McDowell in playing on the controversial new Tour, and will be part of team Crushers GC, captained by Bryson DeChambeau.
"LIV Golf continues to attract the best players in the sport as it builds increasingly competitive fields with each event," LIV Golf chief executive Greg Norman said.

The PGA Tour suspended all of its members who competed in the inaugural LIV Golf event as soon as they teed off at Centurion Club last month, with commissioner Jay Monahan saying the "same fate holds true" for future defectors.
The DP World Tour fined members £100,000 ($A178,000) and banned them from the Genesis Scottish Open, which is co-sanctioned with the PGA Tour, a stance which has since prompted the threat of legal action from 16 players.
