Quintana's next start will come Tuesday against the Dodgers instead of Sunday against the Diamondbacks as originally scheduled, Jesse Rogers of ESPN.com reports.
Tyler Chatwood will make a spot start Sunday, giving the Cubs an extra righty against the righty-heavy Diamondbacks and an extra lefty against the lefty-heavy Dodgers. The change of plans costs Quintana a two-start week and gives him a tougher opponent for his next start, though it likely means he'll gain a two-start week next period.
