Rea will start for the Brewers in Tuesday's game against the Astros, Curt Hogg of the Milwaukee Journal Sentinel reports.
Rea was recalled from Triple-A Nashville over the weekend and was initially expected to operate as a long-relief option, but he'll be thrust back into the rotation after Eric Lauer (shoulder) was placed on the 15-day injured list Monday. In seven appearances (six starts) with the big club this season, Rea has gone 0-3 with a 5.52 ERA, 1.29 WHIP and 25:13 K:BB across 31 frames.
