New York Yankees ace Gerrit Cole has been shut down and is scheduled to visit Dr. Neal ElAttrache in Los Angeles for further testing on his right elbow, according to two sources with knowledge of the situation.

Manager Aaron Boone on Tuesday ruled Cole out for Opening Day. He is expected to begin the season on the injured list.

Cole underwent an MRI on the elbow in Florida earlier in the week after reporting "discomfort." Boone told reporters the right-hander did not bounce back as expected between outings.
