Twins first baseman Justin Morneau will have neck surgery on Wednesday to remove a herniated disk fragment, keeping him out another six weeks, according to an ESPN.com report. Morneau had already been battling a sore left wrist that landed him on the 15-day disabled list and had been in a cast to try to stablize that injury while also resting his neck. After seeing a specialist, he and the club made the decision to have the surgery.
