The point guard has missed the team's last five games after undergoing cortisone and platelet-rich plasma injections in both of his ankles and has started on the bench this evening.
The 29-year-old told ESPN: "That's the plan. It took me a while last year. It wasn't like it happened overnight. It was a little process but you know I'll only know until I go out there.
"[Yesterday], we didn't do much in practice for me to even tell. We didn't go up and down or anything so mentally it was just another workout today."
Williams has struggled with a string of ankle injuries throughout his NBA career.
