Positive drug test

Naden provisionally suspended after positive drug test

Naden, whose place in Penrith's game-day 17 was one of the storylines of grand final week, admitted using the recreational drug to club officials last month.

His positive A-sample for "metabolites of cocaine" was registered in a post-game test conducted by Sport Integrity Australia after the October 25 decider.

Cocaine is prohibited in-competition by both the World Anti-Doping Agency (WADA) and the NRL's Anti Doping Policy, with Naden now serving a provisional suspension as a result.

Tuipulotu situation causing headaches for Umaga

Tuipulotu found out in November last year that he'd returned a positive drugs test and was sent home from the All Blacks end of year tour in Europe for what was described as "personal reasons" at the time.

In a statement on the weekend, New Zealand Rugby said it had strict confidentiality obligations surrounding the case and wouldn't offer any further comment.
