DeGrom injury is a pinched ulnar nerve in his right elbow, which will require surgery, sidelining him for three months. A determination as to when he will have the operation has not yet been made, as there is the slim chance he may still pitch this season, if the Mets advance far in the playoffs, Newsday reports.

EDGE Analysis

The surgical procedure will remove scar tissue that has developed around the nerve, pinching it, a situation that is somewhat common following Tommy John surgery, which deGrom underwent in October 2010. DeGrom won't injure the arm additionally by pitching, as an MRI showed no damage to the ligament, but the uncertainty and probability of a flare up likely will result in the operation happening sooner rather than later.
