Meanwhile, Falcons coach Mike Smith says running back Steven Jackson will miss Sunday's game at Miami with a thigh injury.
Smith says Jackson has a short-term injury. He provided no further details.
The announcements Tuesday came one day after the Falcons placed two other starters, defensive end Kroy Biermann and fullback Bradie Ewing, on injured reserve with season-ending injuries from a win over St. Louis.
Weatherspoon sustained a foot injury in Sunday's game and didn't return. While the team didn't specify the specifics of his injury, it was clearly serious with the Falcons opting to use a special one-time-only provision of injured reserve, which allows the linebacker o return to practice in six weeks and rejoin the roster in Week 11.
Jackson left last week's win over the Rams after scoring in the first quarter on an 8-yard pass from Matt Ryan. Smith says Jacquizz Rodgers and Jason Snelling will share the work at running back against the Dolphins.
