Before landing on the DL, Glasnow made two starts with the big league club, going 0-1 with a 5.40 ERA.
With Pittsburgh's rotation still in flux, Glasnow would likely receive some starts down the stretch if he were fully healthy.
• The Pirates training staff continues to monitor Francisco Cervelli after he was plunked in the head by an 82.8-mph changeup from Mike Foltynewicz in the fourth inning of Tuesday night's game. The catcher exited the contest shortly after taking his base.
Cervelli has a history of concussion issues, and his status is still TBD at this time, according to Tomczyk.
While Cervelli was still active for Wednesday's game, Pittsburgh brought up Elias Diaz from Triple-A Indianapolis for the taxi squad.
• Chris Stewart was running the bases before Wednesday's game and continues to hit and catch bullpens as he recovers from left knee discomfort. Tomczyk said Stewart, who has been on the DL since July 4, will catch Glasnow's simulated game.
