Knights five-eighth Jarrod Mullen has had an injury-plagued 2016 NRL season.

Mullen suspended by NRL

The NRL has provisionally suspended Newcastle Knights player Jarrod Mullen under the NRL’s Anti-Doping Policy.

The Provisional Suspension Notice asserts that Mr Mullen returned a positive A-sample for an anabolic steroid, Drostanolone which is prohibited by the World Anti-Doping Agency (WADA) and the NRL’s Anti-Doping Policy. He was tested by the Australian Sports Anti-Doping Authority (ASADA) on November 29, 2016.

Mr Mullen is prohibited from participating in any WADA compliant sport, including Rugby League, while the provisional suspension is in place.

Under the Anti-Doping Policy, Mr Mullen now has the opportunity to have his B-sample analysed.

The NRL will not be making further comment while this process is under way.
