Liriano will have his next scheduled start bumped back to Saturday against the Cubs, Rob Biertempfel of the Pittsburgh Tribune reports.

EDGE Analysis

The Pirates needed to buy time to further evaluate Jon Niese (knee), so they plan to call up Tyler Glasnow to start Thursday, which will effectively push back the rest of the starters a day. As it currently stands, Liriano is expected to face fellow southpaw Jon Lester in the second to last game before the All-Star break.
