Miller originally thought he had some lateral meniscus damage, and hoped he would be able to brace up and return to play by Week 11 — just 17 days removed from the injury. Instead, on December 1, the Bills decided to place him on injured reserve and give his knee time to rest.
On December 7, Miller had exploratory surgery done with the intention of re-positioning the meniscus and cleaning up some cartilage. As we now know, however, that wasn’t all that the medical staff found while Miller was on the table in Dallas.
