Flynn (ribs) has also been diagnosed with a lumbar vertebal fracture and was placed on the 60-day disabled list Wednesday, MLB.com reports.

EDGE Analysis

The Royals revealed earlier this week that Flynn fractured his rib after falling through the roof of his barn, but it appears he may have also wrenched his back in the process. Flynn was initially given an eight-week recovery timetable, but his placement on the 60-day DL means that he'll now be sidelined through at least early June. Even if Flynn is fully recovered from the injury by mid-April, he'd still probably need at least a month to rebuild arm strength and improve his conditioning, so it's probably a prudent move for the Royals to delay a potential return until June while opening up a 40-man roster spot in the process.
