Brandon Lyon looks like he's headed for season-ending surgery for his biceps tendon.
Alyson Footer says that:
Brandon Lyon was examined by Dr. Yocum today and he agreed with Dr. Lintner's earlier diagnosis. Surgery likely. Not scheduled yet.
I feel bad for Lyon. I really do. It's been obvious for some time that Lyon hasn't been right, basically since Opening Day. But it's worth it to try to salvage his contract for next year, both in terms of how much he'll get paid next year, and how much he should get paid not to pitch this year.
