Montgomery will take Jake Arrieta's place in the rotation for Sunday's contest against the Reds, Bruce Levine of 670thescore.com reports.

EDGE Analysis

With Arrieta resting his hamstring, manager Joe Maddon will turn it over to Montgomery for the regular-season finale, and see how far he can take them before turning it over to the bullpen. During his latest start against the Rays on Sept. 19, Montgomery went six innings, but has appeared out of the bullpen twice in the past week, although he hasn't pitched since Tuesday so he should be able to last a fairly decent time on the mound.
