Eflin had surgery on his right knee and was transferred to the 60-day disabled list, Stephen Gross of the Morning Call reports.
As had been expected, Eflin's season has officially come to an end. It's expected that Eflin will undergo surgery on his left knee in the coming weeks. However, Philadelphia is optimistic that the surgeries will end Eflin's knee issues, making it possible for him to continue developing once he's healthy again.
