What happened: The Yankees are officially describing Aaron Judge's injury as a bone bruise in the ribs that can be felt in his right shoulder. Manager Aaron Boone said the issue impacts Judge when he swings. The team's wording clarifies the nature of an injury that had already kept Judge off the field.

Why it matters: The diagnosis explains why Judge was held out of the Yankees lineup earlier in the day. As New York's middle-of-the-order anchor, a swing-impairing ailment threatens the club's run production until he is cleared.

What to watch: Watch for whether Judge requires imaging or an injured-list stint, and any timeline Boone offers for his return to the lineup.
