NRL star Mullen handed four-year ban

Updated: 

Former Newcastle Knights playmaker Jarrod Mullen has been handed a four-year ban for anti-doping breaches.

Mullen, 30, was given the suspension under the NRL's Anti-Doping Policy on Wednesday.

The tribunal said the violations Mullen committed were: "presence of the prohibited substance Drostanolone, an anabolic steroid" and "use of the prohibited substance Drostanolone".

Mullen's ban expires on January 16, 2021, having begun on January 17 this year. He has 21 days to appeal to the Court of Arbitration for Sport (CAS).

"As we have said all along, this has been a disappointing matter for all parties," Knights chief executive Matt Gidley said.

"We wish to reiterate this matter took place independently of the club.

"It is important to acknowledge Jarrod made a significant contribution to the club over a long period of time and that adds to the disappointment in how he now departs the club.

"We wish him and his family all the best for the future."

Mullen played 211 NRL games for the Knights, having begun his career at the club in 2005.
