Williams, the Tigers' senior development coach and 2004 Port Adelaide premiership mentor, was diagnosed with lymphoma and has undergone testing to determine the extent of the problem.
He is still waiting on results.
Speaking on SEN on Thursday afternoon, Richmond’s general manager of football Dan Richardson said Williams had been at the club all week.
"He's going well," Richardson said.
"He's upbeat, as Choco always is. He's still waiting on some final results of some testing he's had over the last week or so, and hopefully over the next week we'll know a little bit more.
"He feels fine so hopefully that's a good sign."
Williams remained in Melbourne while the playing list headed to Townsville in North Queensland for a pre-season training camp.
