Canterbury and New Zealand star Sonny Bill Williams has admitted to having a drink problem after two off-field incidents this season.
Williams has suffered a host of injuries over the last three years
The latest incident saw the 21-year-old fined for urinating in a public place after leaving a Cronulla nightclub.
"I've let a lot of people down over the last couple of months, particularly myself," he said. "The bad publicity that I've had has been alcohol related.
"I'll be seeking professional help with regards to alcohol."
The loose forward announced himself on the international scene in 2004 with a series of superb displays for the Kiwis but has since suffered a list of ankle, shoulder and knee injuries.
And he has now placed himself on an alcohol ban and will undergo counselling.

"I've been in this position before and this time I've come to the conclusion that enough's enough," he added.
"With the help of the club I'll be taking drastic measures to make sure this doesn't happen again.
"I'll be seeking professional help with regards to alcohol and until myself and the club feel this is under control I'll be off the drink."
And Williams has been warned by the Bulldogs that his future at the club could be under threat if there are further incidents.
"It is a big step for anyone to admit they may have alcohol problems. Sonny has taken that step," said Canterbury CEO Malcolm Noad.
"He has also taken the next step of asking for assistance in addressing this issue and we are fully supportive of him.
"It has also been pointed out to Sonny that should there be any further incidents he's in danger of cutting short a very promising career."
