Kopech (calf) will return to start Thursday's game at High-A Salem, the Boston Globe's Alex Speier reports.

EDGE Analysis

He missed the last three weeks with a calf injury, but will make his second minor league start of the year Thursday. Kopech remains one of the Red Sox's top pitching prospects, and could really do with a run of good luck here after missing time this season with a various injuries (one self-inflicted) in addition to 50 games at the end of last season due to a PED suspension.
