Cubs' Gerardo Concepcion: Set to be optioned Monday

Concepcion is expected to be optioned to Triple-A Iowa on Monday, Gordon Wittenmyer of the Chicago Sun-Times reports.

The move won't become official until later in the day, but Concepcion will head back to Iowa, as the Cubs bring up veteran right-hander Joel Peralta. Concepcion has made a trio of appearances for Chicago since joining the team last weekend, and he's allowed one earned run on two hits through 2.1 total innings.
