Manny Machado will undergo reconstructive surgery on his left knee. Machado received two opinions on his knee last month and decided at that time to rest and rehab rather than go under the knife. However, his MRI results were then sent to multiple other doctors, and it was ultimately decided that he's better off going ahead and having the operation. He'll need 4-6 months of rehab, which means it's possible he might not be ready for the start of the season. At the very least, he'll be brought along very slowly in spring training.
