On Week 14 of the 2016 NFL season, Dolphins quarterback Ryan Tannehill suffered the first major injury of his still young career, when defensive lineman Calais Campbell crashed into his knee and caused what was originally diagnosed as a sprained ACL and MCL.
In essence, this means that Tannehill only partially tore his knee, which gave the team hope that surgery could be avoided. This is exactly what took place, as Tannehill decided to forego going under the knife and let his body heal naturally, the way it's supposed to.
Every indication since then has stated that Tannehill is ahead of schedule on his recovery, and the now veteran quarterback is back to normal and looks as good as he ever has, so says head coach Adam Gase who spoke on the topic this past Friday during a press conference.
