Right-hander Michael Tonkin has been recalled from Triple-A Rochester, Red Wings manager Mike Quade told reporters after Wednesday's game.
The corresponding move wasn't yet known, but Twins setup man Casey Fien was removed from Wednesday's 10-7 loss to the Detroit Tigers in the eighth inning. Afterward, Twins manager Paul Molitor said Fien was dealing with a "tender shoulder."
Molitor said Fien likely would be sent for additional tests on his shoulder.
Fien, who has made 73 appearances in each of the past two seasons, was off limits for an April 10-12 series at the Chicago White Sox with what was described as a muscle strain behind his throwing shoulder.
