INDEPENDENCE, Ohio — Guard Mo Williams has informed the Cavaliers he’s officially retired.

Williams has waffled on whether he would return all summer and the 33-year-old told the Cavs about his plans Monday shortly before the NBA champions held their media day.

Despite Williams’ retirement and losing Matthew Dellavedova as a free agent, Cavs general manager David Griffin said the team is “comfortable” at point guard and the team would not immediately look to add another. Kyrie Irving will start with rookie Kay Felder as his backup.

Williams played two stints with Cleveland. He was not in coach Tyronn Lue’s rotation for much of last season, but wound up playing in the NBA Finals when Dellavedova struggled.

Also, Griffin said the team has made “an incredibly competitive and aggressive offer in re-signing” free agent J.R. Smith.

Smith had a vital role in Cleveland’s championship run last season.
