Lorenzen (personal) is expected to rejoin the Reds on Friday, C. Trent Rosecrans of the Cincinnati Enquirer reports.
Lorenzen was placed on the bereavement list Tuesday to attend to a family issue, but it looks as though he'll only miss the minimum three days. Once Lorenzen is activated, the Reds will need to make a move to free up a spot on the 25-man roster. Tim Adleman came up from Triple-A on Tuesday, and he's the primary candidate to be optioned.
