Astros manager Joe Espada said Tuesday that McCullers (forearm) will not throw for a few days, Chandler Rome of The Athletic reports.
Espada noted that McCullers' throwing arm was not responding well between bullpen sessions, and the 30-year-old will rest while the team figures out next steps. It's a step back for McCulers, who hasn't pitched since the 2022 World Series and is working his way back from June 2023 surgery to repair the flexor tendon and remove a bone spur in his right forearm.
