Yankees' slugger Aaron Judge has been diagnosed with a stress fracture of his first right rib, per manager Aaron Boone. The 27-year-old will rest for the next two weeks before he is re-evaluated.

The public diagnosis, while vague, at least ruled out a fracture, which would have been more serious. But the injury is evidently severe enough that Judge will be sidelined for at least a while.

“It’s probably an injury that dates back to last September,’’ Boone said of a play in which Judge dove in right field, attempting to make a catch in a Sept. 18 game against the Angels.
