Cape Town - Blues second-rower Patrick Tuipulotu has allegedly been tested positive for a banned substance.
According to Fairfax The All Black lock was tested last year for performance enhancing drugs before New Zealand's Test against France which led to the player going back to New Zealand, citing personal reasons for his departure.
The New Zealand Herald stated that a representative from the Blues refused to comment on the matter. But the lock has yet to take part in the Blues pre-season preparations and won't do until next week.
Late last year New Zealand rugby announced that all professional players will be tested for banned substances during the off-season.
Tuipulotu is a valuable asset to the All Blacks and the Blues after playing for his club 34 times and the All Blacks on 12 occasions.
