St. Louis Cardinals pitcher Chris Carpenter has been diagnosed with nerve irritation, causing weakness in his right shoulder.

It is not related to a cervical disc injury Carpenter suffered earlier in spring training, the Cards said Friday.

Carpenter will return to training camp next week, but there is no timetable for his return to the mound.
