Anderson was placed on the 10-day injured list prior to Wednesday's game against the Rockies with a right middle finger blister, Tom Haudricourt of the Milwaukee Journal Sentinel reports.
Apparently Anderson had a blister and callous burst open during his pregame warmup, prompting the Brewers to scramble and make the roster move just minutes before first pitch. Corbin Burnes was called up from Triple-A San Antonio in a corresponding move, though Freddy Peralta (shoulder) -- who will be activated off the IL to start Thursday -- should round out Milwaukee's starting rotation.
