Rugby remained relatively free of drugs in 2011 despite two violations of anti-doping rules being reported.
In total, 170 tests were performed by Drug-Free Sport New Zealand (DFSNZ) in the calendar year to date. Neither of the two violations detected involved any illegal substance or a player attempting to enhance performance.
The first saw a member of the Bay of Plenty pre-season training group suspended from all rugby for two years after he left a training session without giving a required urine sample.
The other case also involved a Bay of Plenty representative, who was mistakenly given probenecid by his team doctor - a substance which, while not performance-enhancing, is banned because it can act as a masking agent for other illegal substances.
He was suspended from rugby for one week after the NZRU anti-doping tribunal determined the player had no intention to enhance his sporting performance.
