Chicago Cubs ace and Cy Young award winner Jake Arrieta has a blister, which could put his Opening Day start in jeopardy, manager Joe Maddon told reporters in spring training on Friday.

“Blisters can be funny,” Maddon said. “Right now, we haven’t called off the jam yet. But you want to look at it, I would say, after maybe another day or two [and] then try to make our best determination at that point.”

Arrieta is scheduled to throw a bullpen session on Saturday. He is coming off a start where he surrendered five runs in 1/3 of an inning with 34 pitches.
