Newcastle coach Nathan Brown has refused to comment on Shaun Kenny-Dowall's possible future with the NRL club after the former Rooster was sentenced for cocaine possession.
Kenny-Dowall received a 12-month good behaviour bond and was spared a conviction at Downing Centre Local Court on Tuesday after pleading guilty to possessing a small amount of the drug at a Sydney nightclub.
The Sydney Roosters suspended the 29-year-old following the arrest in May and released him from his contract last week.
He had reportedly been negotiating a contract with the Knights before his arrest.
Brown told reporters on Tuesday it would be inappropriate to comment on whether the club had made a decision about Kenny-Dowall's future.
"When something like this occurs it heads to people above me," Brown said.
Knights chairman Brian McGuigan told Fairfax Media last week he had concerns about signing Kenny-Dowall and wanted to avoid players who might bring scandals to the club.
Kenny-Dowall played 224 games with the Bondi-based side, making his debut in 2007 and playing in the Roosters' grand final losses in 2010 and 2013.
