Texas Rangers pitcher Matt Harrison is continuing to rehab his injured back and is not expected to rejoin the team until September, reports MLB.com.

Harrison starts a throwing program on Monday and could throw on flat ground for four to six weeks before being allowed to throw off a mound.  Harrison underwent an operation on April 23 to repair a herniated disk in his lower back and was transferred to the 60-day disabled list on May 25.

"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.
