Isaiah Stewart is set to miss at least two weeks with a moderate left ankle sprain, disrupting Memphis’s centre rotation before the regular season has begun.
The Grizzlies announced on 9 October that Stewart would be reevaluated in two weeks, according to The Commercial Appeal’s injury update. That schedule leaves him unlikely to be available for the 21 October opener against Utah, with Zach Edey and Quinten Post positioned to handle the bulk of the centre minutes in his absence.
BasketNews also reported the team’s announcement, confirming the diagnosis following Stewart’s early exit from Memphis’s preseason opener against Atlanta.
A reassessment, not a return date
Stewart hurt his ankle on 5 October after falling while contesting a shot at the rim against the Hawks. He left in the first quarter after playing just two minutes and did not return, The Commercial Appeal reported.
The new update gives Memphis a clearer assessment of the injury, but not a confirmed comeback date. Two weeks from the announcement falls on 23 October — after the season opener.
That distinction matters: a reevaluation is a medical checkpoint, not clearance to play. The announced timeline does not establish when Stewart will resume full basketball activity or become available for games.
The sensible expectation is that Memphis will begin the season without him. That is an inference from the timetable, rather than a separate game-specific ruling for the Utah matchup.
Edey and Post move to the front of the queue
Stewart’s absence removes one of Memphis’s principal options at centre and makes the remaining preseason games more important for settling the rotation.
The Commercial Appeal expects Edey and Post to receive most of the minutes at the position. RotoWire’s update likewise identifies Post as the likely interim backup behind Edey.
That gives Post the clearest immediate opportunity: a more direct route into the regular rotation while Stewart recovers. It does not, however, establish a guaranteed workload for either remaining centre. Losing a rotation player creates minutes to distribute; it does not tell us exactly how the coaching staff will distribute them.
For Memphis, the immediate task is to establish a workable centre rotation without treating Stewart’s next assessment as a fixed endpoint.
Fantasy: watch the role before chasing the opening
Fantasy managers should not pencil Stewart back into line-ups as soon as the two-week window ends. His next medical update, rather than the calendar alone, will determine whether a return is approaching.
Post is worth monitoring in deeper leagues because the injury creates a clearer path to backup minutes. That makes him a watchlist option, not an automatic pickup across every format. His actual playing time will be more useful than the opportunity on paper.
Edey remains the leading centre option, but Stewart’s absence alone is not enough to project a specific minutes increase or a jump in production. The actionable change is a thinner Memphis rotation — with Post’s role and Stewart’s recovery the next things to track.
