Whitlock (elbow) was placed on the 15-day injured list Friday with right elbow ulnar neuritis, Ian Browne of MLB.com reports.

EDGE Analysis

The right-hander last pitched Saturday, surrendering five run over four innings against the Brewers. The move to the IL is retroactive to April 25 (Tuesday), so if he can make it back in the minimum amount of days, he'll rejoin the Red Sox rotation May 10. That being said, considering it's an elbow injury on his throwing arm, it's hard to predict any sort of timetable for Whitlock's return. In the meantime, Brayan Bello was recalled from Triple-A Worcester and will replace Whitlock in the rotation Saturday versus Cleveland.
