Furbush (shoulder) will throw a simulated inning Saturday, Bob Dutton of the Tacoma News Tribune reports.

EDGE Analysis

Furbush was able to throw a successful bullpen session earlier in the week and he'll progress to a simulated outing Saturday. Given the length of time Furbush has been on the shelf, he may need a few more simulated games and bullpen sessions before the Mariners send him out for a rehab assignment.
