Manager Aaron Boone said that Severino (shoulder) will face live hitters later this week, Marly Rivera of ESPN.com reports.
Severino's Monday bullpen session figures to have gone well given that he's now progressing to facing hitters. Assuming he continues to progress without any setbacks, the right-hander could start a rehab assignment sometime within the next week, which would likely set him up to join the Yankees' bullpen before the end of the regular season.
