A drug overdose in December reportedly sent former NRL star Jarrod Mullen to hospital in a critical condition.
The Daily Telegraph reports the 31-year-old spent two days in intensive care following the incident.
He has since undergone rehab after the NRL were notified of the situation and offered help.
Mullen is currently serving out a four-year doping ban from rugby league after testing positive to the prohibited steroid Drostanolone.
The shock reports of a drug overdose come after Mullen was named as a target of a police investigation.
He is at the centre of a probe over his alleged involvement in the supply of cocaine, the Daily Telegraph and Channel Nine report.
The reports say Mullen has not been charged by police.
“Strike Force Castlestead was formed in September 2018 to investigate and dismantle an alleged drug supply syndicate operating across the Newcastle City and Lake Macquarie Police Districts,” NSW police said in a statement.
“Since December 2018, 5 search warrants have been executed by Strike Force detectives and 10 people have been arrested and charged in relation to a range of matters including ‘supply a prohibited drug of large commercial quantity’ and ‘knowingly participate in criminal group’.
“Investigations by Strike Force Castlestead continue and further arrests are anticipated.”
