Rea is scheduled to start Friday against the Cubs, Adam McCalvy of MLB.com reports.
Rea gets the ball in place of Brandon Woodruff, who won't make another start for the NL Central champions until the wild-card round of the playoffs. The 33-year-old right-hander holds a 4.74 ERA, 1.22 WHIP and 104:38 K:BB in 119.2 innings (21 starts, four relief appearances) this season with the Brewers.
