Brieske will have his contract selected by the Tigers on Saturday and start at home against the Rockies, Evan Woodbery of MLive.com reports.
Brieske has made two appearances at Triple-A Toledo this year and has struck out nine while giving up five runs in 10 innings. The right-hander will make his major-league debut as Saturday's starter, but his status on the big-league roster following the outing will likely depend on when Matt Manning (shoulder) and Casey Mize (elbow) are cleared to return from the injured list.
