White Sox left-hander John Danks has a grade I tear in the subscapularis area of his pitching shoulder and will be out indefinitely.
Danks had an MRI done on Monday and met with Sox doctor Gregory Nicholson.
Danks said he was told that he will not need surgery.
"It's not thought to be anything real major,'' Danks said. "Just get some rest and get back it.
"It's frustrating because it feels good one day and then crap the next. It's good to know what we're dealing with.''
Danks said the MRI looked similar to the first one he had when he went on the disabled list May 20.
"When you hear the word 'tear' it's kind of scary. But I don't think it's anything super major
"It's just a bummer that it will take longer to get back than we first thought.''
