Tiger Woods injured his right hand in his final round on Sunday at The Masters and after said a 'bone kind of popped out'.
Woods appeared to hit a hidden tree root when playing his second shot out of the pine straw on the ninth.
"A bone kind of popped out and a joint went out of place but I put it back in," Woods said.
"It hurt. It definitely hurt. I didn't know there was a tree root there. I drove my hand or drove the club straight into it. It didn't move. But my body kept moving.
"There was a little joint that popped out and I was able to somehow put it back in, which didn't feel very good, but at least it got back in and I could move my hand again."
Jordan Spieth set out to defy the odds and move a step closer to a first major title as the 79th Masters resumed at Augusta National on Friday.
Spieth held a three-shot lead overnight after carding a superb opening 64 which was just one shot outside the course record and the lowest score recorded in men's major championship history.
The last player to hold the outright lead after the first round and go on to win was Ben Crenshaw in 1984, although Trevor Immelman was joint leader on his way to the green jacket in 2008.
But Spieth showed no signs of faltering as he picked up birdies on the second and fifth to move to 10 under par and four shots ahead of Australian Jason Day, with Ernie Els, Charley Hoffman, Justin Rose and Sergio Garcia another stroke behind.
All eyes were on Rory McIlroy as he began his bid to complete the career grand slam on Thursday, but it was Ryder Cup team-mate Justin Rose who made a flying start to the 79th Masters.
McIlroy is looking to join Gene Sarazan, Ben Hogan, Gary Player, Jack Nicklaus and Tiger Woods in winning all four grand slam titles by claiming a first green jacket at Augusta National.
But after a drive of more than 320 yards on the opening hole and an approach to 10 feet, the 25-year-old missed out on a first ever birdie on the first at the 23rd attempt.
The world number one then hooked his drive on the second into the trees and ended up in a narrow creek, but after taking a penalty drop was able to pitch out to the fairway and hit a superb approach to save par.
McIlroy was four shots off the early pace being set by American Charley Hoffman, who had hit the first shot of the tournament at 7:45am - following the traditional opening ceremony - and was four under par with two holes to play.

Adam Scott ended decades of Australian disappointment when he became the first player from his country to win the Masters with a gripping playoff victory over Angel Cabrera at a rain-soaked Augusta National.
Scott sealed the win with a 15-foot birdie putt on the second extra hole, the par-four 10th, moments after Argentine Cabrera had narrowly missed his attempt from 18 feet.
China's teenage golf sensation Guan Tianlang incurred the wrath of Masters officials on Friday, receiving a rare penalty that almost ended his amazing debut in the year's opening major.
Rules officials imposed a one-stroke penalty on the 14-year-old for playing too slowly during his second round at Augusta National, but he survived to make the cut and seal the award for the best amateur player.
Rory McIlroy's chances of winning this year's Masters took a hammer blow as he suffered a collapse, almost as bad as last year's on a dramatic day in Augusta.
McIlroy shot a 5 over-par 77, which included two double bogeys and two bogeys on the front nine.
From joint third overnight and only one off the lead, he finished the day tied in 27th, ten shots off the lead going into the final round.
