Just when the Yankees’ growing list of walking wounded was beginning to get better, the news on Luis Severino’s shoulder was not what they’d hoped.
An MRI on Tuesday revealed the Yankees’ ace has a Grade 2 lat strain, according to The Post’s George A. King III — a second, separate shoulder injury that stemmed from rehabbing his inflamed right rotator cuff.
The new injury will keep the 25-year-old from throwing for another six weeks.
