Red Sox's Chris Martin: Undergoes MRI on arm

Martin underwent an MRI on his right arm and may be placed on the injured list before Sunday's game against the Angels, Christopher Smith of The Springfield Republican reports.

Smith reports that Martin's MRI occurred on the biceps and shoulder area. The Red Sox are currently dealing with several injuries to their pitching staff, so even if the imaging comes back clean there's a good chance that the right-hander heads to the injured list.
