Glasnow (shoulder) will make a rehab start at Double-A Altoona on Monday, Bill Brink of the Pittsburgh Post-Gazette reports.
With this latest news, it seems that Glasnow is still on track for an early-September return. Glasnow's first rehab start will be in the realm of four innings or 65 pitches. The 22-year-old righty had struggled during his two starts before injuring his shoulder, allowing five earned runs over 8.1 innings while walking five batters.
