The Brewers placed Crow on the 15-day injured list Friday, retroactive to Wednesday, with a right forearm flexor strain.
Crow pitched two shutout innings during his last outing Tuesday against the A's, but he appears to have come away from his appearance with forearm problems. He'll be forced to miss at least the next two weeks as a result, and the Brewers will recall Craig Yoho from Triple-A Nashville to fill the open spot in their bullpen.
