Jacob deGrom to undergo MRI after leaving start with injury

The New York Mets are once again facing real concerns about the health of ace pitcher Jacob deGrom.

deGrom missed his last turn through the rotation due to tightness in his right side but was healthy enough to return Sunday against the Arizona Diamondbacks. However, he was pulled while warming up for the sixth inning after experiencing further discomfort in the right side.

After the game, Mets manager Luis Rojas said deGrom will undergo an MRI, throwing his status into question.
