A person informed of Jackson's injury told NFL Media Insider Ian Rapoport on Tuesday that Jackson might miss two to four weeks with a thigh injury. The 30-year-old officially is viewed as "week to week."
What's worse, the Falcons on Tuesday placed Sean Weatherspoon on injured reserve-designated to return after the linebacker suffered a foot sprain in Sunday's contest. This news comes one day after the team announced defensive end Kroy Biermann will miss the rest of the season with a torn Achilles tendon.
With the ground attack struggling, the offense has been decidedly one-sided.
The Biermann and Weatherspoon losses are major blows to a defense that has failed to muster any semblance of pass rush over the first two games of the season.
Biermann was a moveable chess piece for coordinator Mike Nolan, lining up all along the defensive front seven -- and even at safety on occasion. Weatherspoon widely is viewed as the Falcons' most valuable defensive player, capable of rushing the passer and hanging with tight ends and running backs in coverage.
