Buchanan was hit in the arm with a line drive Monday and is dealing with a bruise on his upper right arm, Mark Gonzales of the Chicago Tribune reports.

EDGE Analysis

This is the best case scenario for Buchanan, who had to be removed after being hit with a comebacker. The bruise is on his throwing shoulder, so he could be held out slightly longer than expected, but he should be back within the week. He'll be considered day-to-day until the Cubs specify otherwise.
