Gonzalez (groin) will head out on a rehab assignment Sunday, MLB.com's Scott Merkin reports.

EDGE Analysis

The White Sox haven't specified which affiliate Gonzalez will join, but the plan is to have him back by next weekend, when rosters will have expanded to 40 men. Once activated from the DL, Gonzalez will likely replace Anthony Ranaudo as the fifth starter in the Sox's rotation.
