Arrieta (thumb) is scheduled to throw a bullpen session Thursday, Meghan Montemurro of the Chicago Tribune reports.

The 35-year-old was bumped from Tuesday's start and landed on the injured list with a right thumb abrasion, but he's isn't expected to be sidelined for long. Arrieta could return next weekend at Detroit after spending the 10-day minimum on the shelf if he avoid any issues during the bullpen session.
