“He still gets fatigued very easily. He still has times there when he gets nauseous and things like that. Unfortunately the only thing that is going to heal is time.”
Parr said Scott was one of the toughest players he had met but admitted the former Queensland enforcer initially struggled when told of the long recovery process.
“When you are used to bouncing back quickly from injuries or illness because he is such a good athlete, to be told that it could be a 12- to 24-month process, that’s hard to take,” he said. “He’s one of the toughest blokes I have met. He’s used to dealing with pain, he’s used to being high energy.
“So that’s the struggle for him at the moment, to make sure he is looking after himself and taking things easy.”
Scott, 34, was set to retire at the end of the 2019 NRL season before his 268-game career – all with the Cowboys – was cut short by the health scare.
But Parr said Scott would still be a part of the NRL club.
“He will certainly be part of our club going forward. We love him a lot, he will have a role to play,” he said of Scott, who played 22 Origins and 22 Tests. “But as it stands at the moment it is small steps.”
