Due to Holmgren’s thin frame, the team signed Isaiah Hartenstein to fill in as the starting center, who could match up against the physical centers while also resolving their troubles with rebounding. Unfortunately, he suffered an injury that is going to sideline him for over a month, so they made an emergency signing with Alex Reese.

“In wake of Isaiah Hartenstein injury, the Oklahoma City Thunder are signing C/F Alex Reese to a non-guaranteed standard deal, agent Billy Davis told ESPN. Reese quit basketball in 2021 after 4 years at Alabama, was a bartender for a year, then played abroad and now has NBA deal,” Charania reported.
