All Blacks and Crusaders winger Zac Guildford will be suspended from the first four weeks of the rugby season, following a New Zealand Rugby Union misconduct hearing into incidents in the Cook Islands last month.
The misconduct hearing followed reports of Guildford's alcohol-related behaviour which the NZRU has deemed were unprofessional and brought the game into disrepute.
The suspension means Guildford is not able to play in the Crusaders' first three pre-season fixtures in February against the Highlanders in Greymouth, the Hurricanes at Mangatainoka, and against the Rebels in Australia, as well as the opening match of the Super 15 season, against the Blues at Auckland's Eden Park on 24 February 2012.
He will be eligible for selection for the Crusaders week two fixture against the Highlanders in Dunedin, on 3 March.
The NZRU has imposed a number of other sanctions on Guildford including a requirement to undergo alcohol treatment and counselling as directed at his own expense.
