New York - Tiger Woods, the former world number one who has been sidelined since last August, was among those listed Wednesday in an updated field for the PGA Championship later this month.
But whether or not he will actually play is still very much uncertain.
The 14-time major champion, who last won a major at the 2008 US Open, was among 112 players listed for the year's final major tournament on July 28-31 at Baltusrol in Springfield, New Jersey.
Woods, who has not played an event since turning 40 last December, last competed in a major at last year's PGA Championship at Valhalla, when he made a late arrival at the course and missed the cut.
Woods played later in August in Greensboro, North Carolina, but has not competed since undergoing a microdiscectomy last September.
British Open officials announced last week that Woods had withdrawn from this year's event at Royal Troon, the first time since his 1995 major debut as an amateur that he has missed three majors in the same year.
Woods, who has slid to 605th in the world rankings, has said he has no timetable for returning and is working as hard and as quickly as possible to recover and return to competition, but that he is being cautious so that he does not return too quickly and suffer a setback in his rehabilitation.
But Woods also said last month that he did not know if he would be able to return this year.
He has until the eve of the tournament to withdraw from the PGA Championship.
This year's chase for the Wanamaker Trophy will include top-ranked defending champion Jason Day of Australia, world number two Dustin Johnson, an American who comes off victories at the US Open last month and the World Golf Championships Bridgestone Invitational last weekend, third-ranked Jordan Spieth, last year's US Open and Masters winner, and Rory McIlroy, a four-time major winner from Northern Ireland.
US left-hander Phil Mickelson, 46, won the 2005 PGA Championship in its most recent playing at Baltusrol. It was the second of his five career major triumphs.
