Greene was placed on the COVID-19 injured list Friday, Gordon Wittenmyer of The Cincinnati Enquirer reports.
Greene's next start had been scheduled for Monday, but he'll now be sidelined for at least seven days, per Major League Baseball's new COVID-19 IL rules for 2023. He could be back as soon as Sept. 8 versus the Cardinals. The righty allowed on unearned run over 5.1 innings in a win over the Giants in his last start.
