Leading player manager Sam Ayoub has leapt to the defence of his client Blake Ferguson, claiming he is "not at fault" after police rushed to the Roosters winger's home in the early hours on Thursday morning.

As revealed by Fairfax Media, police and emergency services were called to Ferguson's Marrickville home at 5.15am to check on his two children after receiving a bizarre call from Ferguson's former teammate, Paul Carter.

Carter claimed to police that Ferguson's one-year-old child had been drugged but ambulance officers were comfortable this had not happened after checking both of his sons.

Ferguson was not charged or taken into custody and they left the children in his care. His partner was not at the house at the time of the incident.
