The former Penrith and St George five-eighth has accepted an offer by Titans coach John Cartwright to join the squad for pre-season training.
Williams, 24, who is being closely-monitored by Performance Manager Chris McLellan, hopes to gain a full time contract with the Titans.
He is currently signed to feeder club the Burleigh Bears.
“Carty has taken me on board, testing me out to see how I go, see if I still got it,” Williams said.
“I’d like to think I still do, but time will tell, I just gotta put in the hard yards for the pre-season, play the trials and see how I go.”
Cartwright was quick to downplay speculation about Williams joining the squad, but admitted that the former Panther has enormous potential.
He added: “He has a lot of ability, Richie, this is probably the first pre-season he has had in a while so we know what he can do on the field and he is going to get every chance to do that.”
