John Daly says he may have torn ligaments in his right elbow during the first round at the Avantha Masters.

The American says on Twitter his "elbow snapped" when he played a shot Thursday on the ninth hole. He finished at 7-over 79.

Daly posted a photo on Twitter with his right arm in a cast, saying "no bones are broken, possible torn ligaments according to European Tour Docs--getting home for X-rays!"

His management company, Wasserman Media Group, says it is unaware if Daly has withdrawn from the tournament.
