What happened: The Atlanta Falcons placed linebacker Yasir Abdullah on injured reserve and signed safety Jammie Robinson to the active roster from the practice squad. Atlanta also announced standard elevations for defensive end Drake Jackson and linebacker Bralen Trice ahead of tomorrow's game against the Baltimore Ravens.

Why it matters: Abdullah had been managing a hamstring issue and leaves a void in the pass rush after registering four quarterback hits last week. The subsequent elevations of Jackson and Trice supply immediate rotational depth for the defensive front.

What to watch: The Falcons face the Ravens tomorrow night.
