Kopech fractured his right hand (on his throwing arm) after engaging in an altercation with a teammate recently, WEEI's Rob Bradford reports.
The organization is handling the issue internally while continuing to work through a medical plan. This is not the first time Kopech's makeup has popped up as possibly suspect, as he served a 50-game suspension last year for testing positive for a performance-enhancing drug. He is Boston's second-best pitching prospect behind Anderson Espinoza, but it's not hard to find reasons to discount him for off-the-field issues. Continue to monitor his status for an update on his timetable to return to the mound.
