golf: American Dustin Johnson denies he has had a drug problem but admits "drinking to excess" was an issue he had to address.

The 30-year-old, who on Tuesday night announced the birth of his first child, a son, with fiancee Paulina Gretsky, is currently on a voluntary leave of absence from the PGA Tour.

His disappearance from the tour in late July prompted allegations in the United States of a positive test for cocaine - claims which have dogged him for several years but which he has always strenuously denied.

The big-hitting Ryder Cup star has again dismissed the drug claims, revealing his battle has been with alcohol.

"I did not have a problem," he said, talking specifically about cocaine. "It's just something I'm not going to get into. I have issues but that's not the issue."

He added: "Like everyone I'm tested regularly by the Tour and as far as that's concerned ... I haven't failed anything.

"I would drink and drink to excess. The change I made is I just don't do that any more."

Allenby decides to take a break

golf: Australian Robert Allenby has elected to skip this week's PGA Tour event following the incident in Hawaii in which he reported being kidnapped, beaten and robbed.

The 43-year-old has said he has ''no recollection'' of events that unfolded last Friday after he missed the cut at the Sony Open and spent the evening in a wine bar. Allenby has explained that he was found unconscious six miles away in a park with significant facial injuries and missing his wallet, mobile phone, cash and credit cards.

Rather than immediately return to work at the tour event in La Quinta, California, Allenby believes he would be wise to step away, having taken medical advice. He said: "On the advice of my doctor, I have decided to withdraw from this week's Humana Challenge. This will enable me to ensure I am fully recovered prior to rejoining the PGA Tour."

O'Connor finishes tenth in Austria

Winter Sports: American-born Irish snowboarder Seamus O'Connor finished tenth in the Men's Slopestyle World Championships in Kreischberg, Austria.

The 17-year-old produced the best slopestyle performance of his career in the semi-finals and in doing so qualified with the second highest score, 90.33, for yesterday's final. He finished with a score of 54.50 in the final, failing to reproduce Tuesday's display, with USA's Ryan Stassel coming out on top with 97.50.
