Norman, 25, was allegedly found in possession of the prohibited drug, MDMA, as well as a prescribed restricted substance on 20 May.
His barrister, Murugan Thangaraj SC, highlighted that Norman did not consume the substances, and has never returned a positive drugs test.
“There is no doubt about his remorse,” Thangaraj said.
Norman’s legal team asked the court not to record a conviction, but the magistrate refused the request and fined him $400 after a brief appearance at Downing Centre court in Sydney on Wednesday.
Norman has continued to play for the Eels since the incident, most recently starring in last Friday’s win over the Sydney Roosters, but, with his contract set to expire at the end of the current season, his conviction casts doubt on his future at the Parramatta club.
The court appearance is just the latest of a string of controversial moments to hit the Eels this season, and comes in the same week that two sex tapes allegedly featuring Norman were reportedly shopped around media outlets.
Norman’s involvement in the videos is currently under investigation by the Eels, who will report back with their findings to the NRL’s integrity unit.
