Boyd was placed on the 10-day injured list with left arm discomfort Tuesday, Jason Beck of MLB.com reports.

EDGE Analysis

The southpaw will be further evaluated in the next 24 hours, so it's still possible he'll be given a more detailed diagnosis and return timeline in the near future. For the time being, he'll miss at least his next turn through the rotation. He'll be eligible to come off the IL on June 25.
