What happened: The Atlanta Falcons released defensive end Drake Jackson from the practice squad on Tuesday. The team filled the open spot by signing center Gus Hartwig to the unit.

Why it matters: Jackson's departure comes one week after Atlanta added him to the practice squad on Nov. 3. The transaction reshuffles Atlanta's depth on both lines heading into midseason preparation.

What to watch: Atlanta integrates Hartwig into practice work ahead of Sunday's game.
