Weatherspoon ruptured his right achilles in Sunday's win over Carolina, Vaughn McClure of ESPN reports.
Weatherspoon suffered a similar injury prior to the 2014 campaign that forced him to miss the entire season, so this is is not the diagnosis the Falcons were hoping for when Weatherspoon left Week 4's game early with a lower leg injury. A timetable for his recovery has yet to be released, but missing the rest of the 2016 season seems like a very legitimate possibility.
