Perez (illness) was activated from the COVID-19 injured list Tuesday, Pete Abraham of The Boston Globe reports.
Perez has been on the shelf since testing positive for the virus in late August, and he'll rejoin the Red Sox on Tuesday after making one rehab appearance in the minors. The veteran left-hander hasn't fared much better since being demoted to the bullpen with an 8.64 ERA in his past 10 outings.
