The Brewers placed Anderson on the 15-day injured list Monday due to right biceps inflammation, Adam McCalvy of MLB.com reports.
Anderson has pitched well in his most recent stint in the majors, allowing two runs (one earned) with an 11:5 K:BB over 10.1 innings. However, he will now be out at least until the final week of the regular season. Brandon Sproat was called up from Triple-A Nashville to take Anderson's place in the bullpen.
