It was already known that Brewers starter Jimmy Nelson would miss the remainder of the season with a shoulder injury, representing a big loss. What wasn’t clear, though, was whether he’d require surgery. Now, it’s clear that Nelson will indeed go under the knife, MLB.com’s Adam McCalvy reports (Twitter links).

It won’t be known just how serious the injury is — and what kind of repair work is needed — until the surgeons access the joint. That said, it seems Nelson has received at least some cause for optimism; the right-hander suggested he has been told that his labrum may not be in need of significant work.

Clearly, we don’t yet know what to expect coming out of the surgery and won’t until it’s already over. In all likelihood, though, the less that’s done to the labrum, the less recovery time Nelson will need — and the less cause for concern there’ll be for his long-term outlook.
