Bagley continues to progress but is not ready to return, the team said, adding that another update would be provided in three weeks.
Bagley, taken by the Kings with the No. 2 pick in the 2018 draft, has played just 13 games this season, averaging 14.2 points and 7.5 rebounds.
He originally injured the foot in December and missed eight games. When he returned, he aggravated the injury after four games and has not played since.
Bagley also missed 22 games with a broken thumb suffered in the season opener.
Bagley was on the All-Rookie first team last season, averaging 14.9 points and 7.6 rebounds.
