Story potentially has UCL damage in his right elbow, Ken Rosenthal of The Athletic reports.
The exact diagnosis is not yet known, but it would be a huge blow to Story and the Rockies if the shortstop's injury ultimately requires Tommy John surgery. Story, who is in the midst of an MVP-caliber season, exited Monday's game against the Dodgers with a right elbow injury after making a diving stab in the field in the first inning.
