Cortes will undergo an MRI on his left elbow Wednesday, Jack Curry of YES Network reports.
Cortes had been slated to start Wednesday's game against the Orioles, but his immediate future is now cloudy while he awaits the MRI results. The veteran left-hander has been excellent lately, allowing just one earned run over his last 15.1 innings of work and boasting a 1.58 ERA covering his last 40 frames. Marcus Stroman -- whose last outing was a three-inning relief appearance Sept. 17 -- is a likely candidate to start Wednesday's contest. Cody Poteet is also expected to join the club at Yankee Stadium, although it's unclear whether he'll join the taxi squad or be added to the active roster.
