Oh boy. There is growing speculation that Miami Dolphins QB Ryan Tannehill suffered a serious knee injury during practice on Thursday and that he could very well be out for the entire 2017 season. Reports are that Tannehill injured the same knee that he suffered a partially torn ACL in a year ago and that there are rumblings he may have torn it outright. It is often that teams will hold back on injury news if it is serious in nature and give quick updates for minor ailments. Matt Moore would then elevate to the starter's position for the Dolphins and he is one of the best backups in the game. However the Dolphins would be devastated if Tannehill is out for the season and his fantasy football owners in two QB formats would be hurt as well. If Tannehill is done for 2017, it also likely means he played his final game for the Dolphins.
