Manager Alex Cora said Friday that Perez (illness) will throw a bullpen at Triple-A Worcester in the coming days, Ian Browne of MLB.com reports.
Perez completed his quarantine Wednesday and joined the Red Sox for workouts late in the week, but he'll spend some time rehabbing with the minor-league club. The southpaw is slated to make a rehab appearance in Worcester on Sunday and will likely be considered to rejoin the big-league squad afterward.
