The Twins transferred Funderburk (oblique) from the 15-day injured list to the 60-day injured list Thursday, Bobby Nightengale of the Minneapolis Star Tribune reports.
The transaction clears a spot on the 40-man roster for the addition of DaShawn Keirsey. Funderburk resumed throwing in late August as he works his way back from a left oblique strain but now isn't eligible for activation until late September.
