KANSAS CITY -- Royals right-hander Jorge Lopez underwent an MRI on Saturday morning that showed exactly what the Royals initially diagnosed on Friday night: He has a deep bruise on his left rib cage.
There is no indication yet whether Lopez will be able to make his next scheduled start, which would come on Thursday in Detroit.
"He's day to day," Royals manager Ned Yost said. "It's just about [pain] tolerance now."
Lopez left Friday's 8-4 win against the Twins with one out in the fifth inning when the bruise began affecting his breathing.
