American Patrick Reed is set to be punished for foul and homophobic language on the opening day of the WGC-HSBC Champions tournament in Sheshan.
Ryder Cup player Reed, 24, shot a 71 but was heard on TV swearing at himself after missing a putt on the first hole.
The PGA Tour said it would "deal with this matter internally".
Northern Ireland's Graeme McDowell holds a two-stroke first day lead after making seven birdies in his first 12 holes and carding a five-under-par 67.
Englishman Tommy Fleetwood had five birdies and shares second.
Lee Westwood, Ian Poulter and world number two Adam Scott are in a share of eighth place, a shot further back.
Australian Scott, who had four birdies in his 70, is the highest ranked player in the field as world number one Rory McIlroy is absent, the only member of Europe's triumphant Ryder Cup team not competing at the 7,261-yard par-72 Sheshan International Golf Club in Shanghai.
The tournament features 40 of the world's top 50 players and is the second of four events in the European Tour's Final Series, which culminates in the World Tour Championship in Dubai from 20 to 23 November.
German Marcel Siem, who won the first of them last week in Shanghai, returned a level-par 72 with three birdies and three bogeys.
Former US Open champion McDowell, 35, who retained his French Open title in July, dropped two shots in his final six holes but only once had to contend with the thick grass that surrounds the narrow fairways and said: "A big key to this golf course is driving the ball well. I drove it very well today."
Only 27 of the 78-man field broke par, compared with 37 players under par on the first day last year, a tournament American Dustin Johnson won with a 24-under total, when McDowell finished four shots back in third place.
World number three Sergio Garcia had only one birdie in a 74, FedEx Cup champion Billy Horschel made a pair of double bogeys in his 80, while Australian Brody Ninyette had a quintuple bogey eight in a round of 86.
