Former Manly star Lloyd Perrett is taking legal action against his old club, with lawyers alleging he suffered permanent injuries during an “outlandish training regime” back in 2017.

Perrett claims he suffered heat stroke in the session, had a seizure, and was in “a comatose state for two days” which then led to permanent injuries.

Perrett’s lawyers allege the front-rower was deprived of water while training, “with disastrous consequences for his career”.

The session involved a warmup of 20 minutes followed by two 2km time trials which Perrett completed in eight minutes and 23 seconds and 10 minutes and 23 seconds respectively.

Perrett completed one lap of a third 2km time trial before he “collapsed unconscious to the ground”.

The claim alleges Perrett was “not supplied with any water or other fluids during the training session because Mr Dan Ferris, the club performance coach, had directed before the start of the session that there would be no water breaks”.

Ferris is no longer employed by Manly.

Brisbane legal firm Carter Capner Law has filed the claim on behalf of Perrett in the NSW Supreme Court.

“On November 6, 2017, a compulsory pre-season training session was held at Narrabeen Sports Complex at Wakehurst Parkway in very warm conditions,” Carter Capner Law director Peter Carter said.

“Players were instructed to run three successive 2km time trials without water being supplied during the session, at very short intervals.

“During the third time trial Lloyd collapsed and his next memory was waking up in Mona Vale Hospital with a diagnosis of severe heat stroke.

“Despite the injury, Lloyd attempted a come-back, playing 10 or so games in the 2018 season and five in 2019.

“That was the last time he played NRL level.”

Carter said Perrett had been “very successful” at an early stage of his career and his potential losses could well be in the millions of dollars.

The claim filed seeks injury compensation mainly for loss of income.

It alleges the club was negligent in requiring intensive time trial training to be conducted in the prevailing conditions and that precautions ought to have been taken for players’ safety.

Since then the NRL has implemented welfare rules that relate to avoiding heat stress and ensuring player safety in warm conditions.

None of the people who ran the session are still working at the Sea Eagles.

Manly have so far declined to comment on the legal action.

Perrett was 24 when he played his last game.

Perrett debuted for Canterbury in 2014 and notched 24 NRL games across three seasons.

On December 9, 2016, Manly announced Perrett had signed a three-year deal with the club from 2017. Carter Capner Law said the deal was worth $500,000 per season.

Perrett was a member of the Queensland emerging Origin squad in 2016 and 2017.

He spoke to the Sydney Morning Herald last year about the long-term mental and physical impacts of the training incident.

“I was comatose,” Perrett said.

“Six out of 10 people die in this situation. That’s what the nurse told me when I was in hospital.

“I became much more anxious (afterwards). I was even suicidal at points.

“If it wasn’t for my parents, I would have taken my own life. I considered myself to be worthless.”
