Rea won't start Sunday's game against the Giants, but manager Craig Counsell said the right-hander is expected to "be involved" in the pitching plan, Vinnie Duber of the Chicago Sun-Times reports.
Ryan Rolison will instead start Sunday's series finale as an opener, lining up Rea to fill a bulk role out of the bullpen. The 35-year-old surrendered seven runs during his last start but was effective in the three outings prior to that with a 3.57 ERA and 1.13 WHIP over 17.2 innings.
