US Open champion Rory McIlroy has undergone a wrist scan after suffering an injury in the first round of the PGA Championship.
The initial diagnosis revealed that he strained a wrist tendon after striking a tree root on his downswing on the third hole.
The 22-year-old played on in clear discomfort before receiving medical attention on the fifth hole, ending the day tied in 25th place.
“It was dangerous,” McIlroy said in a press conference after his round. “I thought that the tree root was maybe a foot in front of the ball and that I could make contact with the ball and just let the club go.
“It was a sharp pain up my forearm and then there was a little swelling on the inside of my wrist.”
McIlroy will make a decision on whether to play through the rest of the tournament with the injury ahead of his round today.
Earlier this week, the Northern Irishman revealed that he believes he has a good chance of winning his second major of the year in Atlanta.
Elsewhere in the tournament, former world number one Tiger Woods found two lakes and 12 bunkers to score a seven over par 77.
American Steve Stricker sits at the top of the leaderboard after equalling the course record with a score of 63.
