Manning (knee) had X-rays come back negative after leaving Wednesday's start against the Pirates, Jason Beck of MLB.com reports.

EDGE Analysis

Manning was struck on the left knee by a liner during the third inning, and the initial diagnosis of a contusion was confirmed when the X-rays came back clean. The 23-year-old didn't factor in the decision after giving up one run on four hits with four strikeouts and zero walks in three innings. He should be considered day-to-day, and it's currently unclear if he'll be able to make his next turn through the rotation.
