"I haven't thrown in two months," Harrison said. "It would be like starting my offseason throwing program. It's frustrating, but it could be worse. I could have missed the whole year. I want to get it right in the next two months and be back at the end of the year. But it's probably going to be another two months for sure."
The six-year veteran was 0-2 with a 8.44 ERA in two starts this season before being injured.
