Fedde will undergo an MRI on his right side after being scratched from Thursday's Grapefruit League start, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

The Nationals aren't too concerned about Fedde's side issue, but he'll still undergo further examination as a precaution. As long as his MRI comes back clean, he could throw a live BP within the next few days and make another appearance in an exhibition game prior to the end of spring training.
