Kenny-Dowall took part in a weights session yesterday and is expected to train with the side tonight.
Kenny-Dowall was arrested and charged with domestic violence-related offences two weeks ago and he was admitted to hospital because of concerns for his mental welfare.
He missed the Roosters wins over the Warriors and Wests Tigers but coach Trent Robinson says the prolific tryscorer is a chance to be selected for his side's round 22 clash against Newcastle.
"He won't be selected for this weekend (but) he is in a good frame of mind and part of that is training," Robinson said.
"We have to take it day by day. He definitely won't play Friday night (against Canterbury) and then we will assess over the next few weeks, whether he is fit and ready to get back into playing.
"He is much better. I had a good chat with him on Sunday. There is a lot of stress for everyone involved and he is a lot clearer on that and ready to get back into it.
"He came in and did some weights yesterday afternoon and he will come back and start some preliminary training."
After being sidelined for the Roosters past two games, a "welfare decision" the club made in conjunction with the NRL, Kenny-Dowall was hospitalised last week.
The case against Kenny-Dowall is next due in court on Thursday week.
Meanwhile young Penrith player Dallin Watene-Zelezniak is set to make a surprise return to the NRL, just two weeks after being hospitalised with a collapsed lung.
The 19-year-old's career was put on hold after suffering what was believed to be a relapse of primary spontaneous pneumothorax - a genetic condition that results in the accumulation of air in the space between the lung and chest cavity.
But Watene-Zelezniak says his most recent setback was a result of a tackle he suffered.
"It's definitely not the case of what happened last year," he said.
"100 per cent it's not to do with the condition. I'm not sure where people have got that from. I'm the only one that's spoken to the specialists. They've actually seen the x-rays of mine and can actually make a call on it and know exactly what it is."
Watene-Zelezniak has twice been named in the New Zealand test side but is yet to play for the Kiwis having been forced to miss his test debut through injury and suspension.
