Nelson left Friday's game against the Cubs after five scoreless innings despite just 79 pitches thrown, Adam McCalvy of MLB.com reports.

EDGE Analysis

There was no official injury report made, but Nelson appeared to jam his right arm sliding back into first base after hitting a single off the wall in the fifth inning. He pitched a scoreless bottom of the fifth but was removed before the start of the sixth. The Brewers are calling the injury right arm soreness -- not much to go on, for now, so we'll consider him day-to-day.
