The Hornets didn’t say when Williams will return to action, saying “an update on his status will be provided as appropriate.”
Williams took over as the starting center midway through last season after the team traded Mason Plumlee.
Williams played in 43 games with 17 starts as a rookie, averaging 9 points in 19.3 minutes. He was second in blocks per game (1.0), third in field goal percentage (.637), fourth in rebounds (7.1) and fifth in double-doubles (11) among rookies.
The 15th overall pick in last year’s draft out of Duke, Williams became one of 10 rookies since 1999-2000 to record a 20-point game, a 20-rebound game and a five-block game in a season.
