Grizzlies Update Isaiah Stewart Injury Timeline Before Opener

The Memphis Grizzlies announced on Oct. 9 that center Isaiah Stewart will be reevaluated in two weeks after suffering a moderate left ankle sprain during a preseason game against the Atlanta Hawks. The injury is expected to keep the new Grizzlies big man out of the Oct. 21 regular season opener against the Utah Jazz.

According to the Grizzlies and reports from The Commercial Appeal, Stewart injured his ankle while defending a shot at the rim in the preseason opener on Oct. 5. He played only two minutes before leaving the game and did not return.

Stewart also missed Memphis' preseason matchup against the Orlando Magic after the injury. BasketNews reported that the Grizzlies acquired the 6-foot-8 center from the Detroit Pistons during the 2026 NBA Draft in exchange for three future second-round draft picks.

The injury creates an early adjustment for Memphis, which will rely more heavily on Zach Edey and Quinten Post at center, according to The Commercial Appeal. The team has also used forwards Cam Boozer and Taylor Hendricks in center roles during stretches, while two-way player Carson Cooper provides another option.

Before joining Memphis, Stewart spent five seasons with Detroit and became known as a vocal leader for the Pistons. He averaged 10.0 points, 5.0 rebounds and 1.6 blocks per game while shooting 55.0% from the field across 58 appearances during the previous season, according to BasketNews.

The Pistons' decision to trade Stewart had been discussed alongside concerns about his previous availability. Piston Powered noted that he had missed time in recent seasons because of injuries or suspensions, including playoff absences caused by leg-related issues.

Stewart's playing style has centered on physical defense and aggressive rim protection throughout his career. His return timeline will depend on the reevaluation scheduled after the two-week recovery period, while Memphis continues preparation for its regular season opener.
