Roosters coach Trent Robinson was full of praise for his former player Shaun Kenny-Dowall, following news this week that Newcastle have signed the centre.
This came after a tumultuous couple of weeks for SKD, who was involved in off-field drama earlier in the season and while he escaped formal conviction, his contract with the Roosters was torn up.
"He's still got a lot of football left in him," Robinson said.
"He will do them proud, he will represent them well.
"It's good that a club like the Knights have seen an opportunity to pick up a strong player and one of the best in his style of the game."
SKD is the Roosters' second-highest try scorer, with AAP reporting he scored 119 in 224 matches.
On SKD's departure, his contract was until the end of 2017, but options to renew were withdrawn. He was in limbo until the Knights came to the table.
