Cole (triceps) is scheduled to undergo an MRI on Saturday, FOX Sports' Ken Rosenthal reports.

The Pirates will do their due diligence with their star pitcher Saturday after Cole left his start Friday with tightness in his right triceps. According to Rosenthal, the expectation going into the MRI is that Cole will likely miss some time, but the injury isn't believed to be season-ending. More information on Cole's status moving forward will be made available after Saturday's MRI.
