McCullers (shoulder) will not make his scheduled rehab start Saturday, Jake Kaplan of the Houston Chronicle reports.
Manager A.J. Hinch said that the right-hander is "fine," but the team will play it safe and hold McCullers out after he had some trouble bouncing back following Monday's outing. McCullers threw 48 pitches over three innings in his first rehab start for Double-A Corpus Christi, allowing one run on three hits (including a home run). He will not be shut down from throwing entirely, but there is no timetable for McCullers to return to live action.
