"I have not been able to see him. He is not in a state of health for me to take instructions," he said.
Outside of court Watson said he could not confirm statements by the Roosters that Kenny-Dowall would plead not guilty.
"I saw that in the media but I am not sure what the source is," he said. "He is in hospital as an inpatient, I don't have any details. It is serious, he is not well."
Mr Watson said he only spoken briefly to Kenny-Dowall about the case who is at a Wesley Mission Hospital.
"I have not discussed the case with him yet," he said.
It was unclear if Kenny-Dowall would be out of hospital to attend the next court appearance.
"I didn't get a crystal ball with my law degree. I'm not in a position to speak to my client about the matter so I can't usefully add anything at all," Watson said.
The matter was adjourned until August 6.
The decision for Kenny-Dowall to seek medical help was made as a precaution because of the club's concerns about for his wellbeing.
A source has told The Daily Telegraph Kenny-Dowall has been not himself and had gone into his shell since his former partner applied for an apprehended violence order against him last Thursday.
He has been given time off by the Roosters and wasn't considered for selection for Friday night's clash against the Wests Tigers.
He was also rested from last Sunday's 24-0 win over the New Zealand Warriors.
Roosters coach Trent Robinson said the 27-year-old's well-being was the club's primary consideration.
"Shaun won't play this week and he probably won't play next week either," Robinson said today.
"It's not about football at the moment, it is about Shaun's welfare, and making sure he is ok."
Speaking on Sterlo On The Couch on Fox Sports on Wednesday night, Robinson described Kenny-Dowall as "being in a dark place".
While he was not asked specifically about Kenny-Dowall being admitted to hospital, Robinson said: "I've had many chats with Shaun (over the past few weeks).
"It's a tough period for him at the moment. He's in a bit of a dark place.
"He's not in a good enough state to get out there and play."
His teammates, including co-captain Jake Friend, said it was important Kenny-Dowall put health before football.
"I've sent him a message, and he's doing it pretty tough," Friend said.
"He knows we're all supporting him, he's having time to himself to get his head right, and hopefully in the next few weeks he'll be back around the office and into the footy again.
"We're hoping Shaun is back into training and playing as soon as possible, but his frame of mind and his health is first and foremost, and footy doesn't compete with that."
Another Roosters' player Boyd Cordner, said he had also reached out to Kenny-Dowall via text, and was only worried about his wellbeing.
"He needs some time to be around his family at the moment, we support that, and whenever he's ready to come back, we'll welcome him with open arms," Cordner said.
"This club has been through a bit in the past, but at this present time, he's a good mate, and we'll support him all the way."
Teammate Brendan Elliot was given the call-up at the last minute, and retains his place on Friday night.
"Brendan was told the day before the game he would be playing, and for him to come in and play the way he did, the boys really respect and trust him on the field," Friend said.
